NanTun round aluminium blank dog tags (DIY engraved) – 30 pack

What these NanTun blank tags are for

If you like the idea of a pet ID tag but don’t want to choose a ready-made design, these NanTun round aluminium blank dog tags are built around DIY customisation. They’re simple, lightweight identification blanks you can engrave yourself with your pet’s name and any other details you want to include.

On paper, they suit situations where you want flexibility: new adoption, updating old contact details, or matching tags across multiple pets. Because they’re blank, you’re not locked into someone else’s wording or layout. That can be a big deal if your pet’s circumstances change.

Key takeaways (at a glance)

The package includes 30 round aluminium blanks. Each tag is polished and made to be handled without sharp edges, which matters if you’re prepping several tags at once. The design is intentionally “basic”: round aluminium discs with a hole for attaching to a collar, rather than a finished, engraved tag.

It’s also worth noting that these are blank tags. So if you were hoping for fully engraved, ready-to-wear ID plates, you’ll still need to do the engraving yourself.

What to know before you buy

What to know before you buy

A few details from the listing help you judge whether they’ll work for your use case.

First, size: the tag is 3 cm, with a thickness of 1 mm. The hole diameter is 4 mm, which is relevant if you plan to thread them onto a specific ring or style of collar attachment.

Second, material: aluminium. It’s a practical choice for DIY engraving because it’s a straightforward metal for creating clear marks. Still, with DIY engraving, the readability will depend on your engraving tool, your technique, and how bold you make the text.

Finally, there’s the “round blank” aspect: you get the base hardware for personalisation, not a finished ID. If you need something instantly wearable, these won’t be instant.

Where it shines in everyday use

The most convincing part of this pack is the quantity. Thirty blanks means you can keep backups, update tags later, or do a small set for family pets. For example, if you’re sorting IDs for a rescue that needs new contact details, having multiple tags on hand makes the process less stressful.

They’re also the kind of product that works well alongside a simple routine: choose a collar, engrave the tag, attach it, and check that the text is easy to read from a reasonable distance. Over time, you can re-engrave if you change phone numbers.

Limitations you should keep in mind

The main limitation is obvious but important: these are not engraved dog ID tags out of the box. You’ll need an engraving method that can handle aluminium, and you may want to practise on one blank first before committing to the final version.

Also, because the listing specifies a particular thickness and hole diameter, you should check your collar attachment plan. If your existing collar or tag ring setup doesn’t suit a 4 mm hole, you might have to adjust your approach.

Who it’s for (and who should skip it)

It makes sense if you’re comfortable personalising pet ID tags yourself, and you want a bulk set for multiple pets, backups, or future updates.

It might not be a great match if you need a tag that’s ready to attach straight away with no DIY involved, or if you’re worried you won’t be able to create a clearly legible engraving.

Is it worth it?

Should you buy it? If DIY engraving is part of your plan, NanTun’s 30-pack of polished aluminium blanks is a practical way to create custom identity tags without being limited to a fixed design. The stated hole size and thickness give you a clearer idea of how it may fit with your attachment method.

Buy it when you want flexibility, a multi-pet quantity, or the option to re-do the wording later. Skip it if you’re after ready-made engraved tags and want something you can put on immediately. And if legibility is your top concern, it’s worth thinking about whether your engraving setup will produce markings you can read quickly.
