Pet Tags Are a Small Product With a Loyal Market

Pet ID tags are one of the steadiest small products a laser owner can sell. Every new dog and cat is a potential customer, tags get lost and need replacing, and owners reorder when they move house or change a phone number. The blank costs very little, the job runs in a couple of minutes, and the perceived value of a personalised tag that carries a pet's name and a contact number is far higher than the material price suggests.

The catch is that a tag has to survive. It hangs on a collar through rain, mud, and a thousand scrapes against doorframes, and a customer who finds the number rubbed off after two months will not come back. That makes metal choice, marking method, and layout the three things worth getting right before you list a single tag.

Metal Choices: What Each Blank Gives You

Anodized aluminium is the best starting material for a CO2 laser. The anodized layer is a hard coloured oxide sitting on top of bare aluminium, and a CO2 beam removes it cleanly to reveal bright metal underneath. The result is a crisp, high-contrast light mark on a coloured tag, produced directly with no spray and no second step. It is lightweight, quiet on a collar, and available in every shape from bone to paw to circle.

Stainless steel is what customers imagine when they hear "durable," and it genuinely is tough — but it is not directly engravable by a CO2 beam. To mark bare stainless you apply a marking compound such as Cermark or a similar spray or tape, laser it, and the compound fuses into the metal as a permanent dark mark. It adds a step and a consumable cost, but the finished mark is extremely hard-wearing and it is the right choice for a stainless line.

Brass and coated blanks sit in between. Lacquer-coated brass marks well because the beam removes the coating, exactly like anodizing, though the exposed brass tarnishes over time unless re-lacquered. Powder-coated and painted steel blanks also mark by coating removal and are a cheap way to offer bright colours.

• Anodized aluminium — direct CO2 mark, best beginner option
• Stainless steel — toughest, needs a marking compound on CO2
• Coated or lacquered brass — marks by coating removal, tarnishes with time
• Powder-coated steel — bright colours, coating can chip at the edges
• Avoid — plated mystery-metal blanks with unknown coating

What a CO2 Laser Can and Cannot Do on Metal

Be clear with yourself and with customers: a CO2 laser does not cut or deeply engrave metal. It marks the surface — either by removing a coloured anodized layer or by fusing a marking compound onto the metal. That is not a limitation for tags, because a surface mark is all a name and phone number needs, and both methods produce marks that outlast the collar.

On anodized aluminium, the mark quality depends on removing the dye layer without heating the metal so much that the dye bleeds into the surrounding area. That means moderate power and fairly fast speed: start around 15–25% power at 200–350 mm/s on a 40–60 W class machine, and build a test grid on a blank before you run an order. If the mark looks grey and smeared rather than bright, you are using too much heat — raise speed before you lower power.

With a marking compound, the process is different. Apply a thin, even coat, let it dry completely, then laser at moderate power and slow speed so the compound bonds, and rinse the excess off with water and a soft cloth. Too little power gives a patchy mark; too much gives a rough, raised mark that catches on a fingernail. Always ventilate — marking compounds and coated metals produce fumes that should be extracted, not inhaled — and keep air assist on throughout.

Layout and Sizing That Stay Readable

A tag is small, and the most common failure is cramming too much onto it. Prioritise: the phone number matters most, then the pet's name, then anything else. If a tag cannot hold all three legibly, drop to name plus number, or number plus "microchipped" — a tag that cannot be read in bad light is worse than a tag with less information.

Work out your text budget before you design. On a 25–30 mm tag, two lines is usually the practical maximum, and you want a minimum stroke width of about 0.6–0.8 mm and a cap height of at least 2.5 mm for the phone number. Use a simple sans-serif or a clean slab serif rather than a decorative script, which looks charming in the listing photo and becomes unreadable once engraved at 3 mm.

Keep 2 mm clear of the edge and the hanging hole, more on shaped blanks where the outline curves inward. Left-align text rather than centring it when the shape is irregular, because optical centring against a bone or paw outline is hard to judge, and off-centre text is instantly noticeable.

• Priority order: phone number, pet name, extra line
• Minimum cap height: 2.5 mm for the number
• Minimum stroke: 0.6–0.8 mm
• Keep 2 mm clear of edges and holes
• Two lines maximum on tags under 30 mm

Fixturing, Jigs, and Running Small Parts

Small parts move. A tag that shifts even half a millimetre mid-job produces doubled text, and it happens more often than people expect because a honeycomb bed does not grip a thin blank. The fix is a pocket jig: cut 3 mm plywood or MDF with pockets sized exactly to your blanks so each one drops in and cannot slide, and cut a separate labelled jig per shape. Once pocket positions are fixed you can lay out a full bed of ten or twelve tags and run the batch without re-measuring — just keep the jig thin enough that the tag surface stays within focus range.

Use masking tape over the surface for anodized aluminium. It cuts the smoke haze around the mark and makes the bright metal underneath pop. Peel it after the job and wipe with a damp cloth. For compound marking, skip the tape, which interferes with the coating.

Durability: Test Before You Promise

Test your own tags before you claim anything in a listing. Scrub a finished tag with a scotch pad, soak one overnight, and put one on your own pet or a keyring for a month. What you learn in a week at home saves a refund and a bad review later.

Anodized marks are genuinely hard-wearing because the mark is the underlying metal rather than an applied layer, though the surrounding anodizing can scuff on sharp edges. Marks made with a good compound on stainless are the toughest of all and survive years of abrasion. Marks on coated brass or painted steel are only as durable as the coating, so describe those honestly as decorative. A single true line in the listing — the mark is permanent but the surrounding finish can scuff — sets expectations and prevents disputes.

Pricing and Listing Tips for Sellers

Tags are cheap to make and easy to underprice. Add up the blank, split ring, compound, packaging and your time, then remember that personalisation is the value the customer is buying. Single custom tags typically sell in the $12–25 range, with stainless and double-sided options at the top, and bundles — a tag plus collar charm, or two tags for a two-dog household — lift average order value with almost no extra machine time. Offering both sides is the strongest upsell: name on the front, number and a medical note on the back, for a minute more run time. Just make sure your jig lets you flip the blank into an identical position, or the back will be misaligned.

Photograph in daylight against a plain background, include a scale reference so buyers understand the size, and show a close-up of the mark. Most tag complaints come from size expectations, not quality, and one clear photo with a coin or a ruler solves it.

FAQ

Q: Can a CO2 laser engrave stainless steel pet tags directly?

Not directly. A CO2 beam will not remove bare stainless, which is why you use a marking compound that fuses to the metal under the beam and leaves a permanent dark mark. Apply it thin, let it dry, laser at moderate power and slower speed, then rinse. Anodized aluminium is simpler for CO2 owners because the beam marks it directly by removing the coloured layer.

Q: How do I stop the phone number from becoming unreadable?

Design for size, not for looks. Use a plain sans-serif at a minimum 2.5 mm cap height, keep strokes above 0.6 mm, and drop to two lines rather than shrinking text to fit a third. Always engrave one test tag and read it from arm's length in normal room light — if you have to squint, the customer will.

Q: Will the engraving fade or rub off over time?

On anodized aluminium the mark is the exposed metal beneath the anodized layer, so it does not rub off, though the surrounding colour can scuff on sharp edges. Marks made with a quality marking compound on stainless are extremely durable and commonly last for years of daily wear. Coating-removal marks on painted or lacquered blanks are only as durable as that coating.

Build a Tag Line That Reorders Itself

Start with anodized aluminium in two shapes, build a pocket jig for each, and keep a test grid photo of your proven settings so every batch matches. Add stainless with a marking compound once the workflow is smooth.
