NanTun Rectangle Aluminum Blank Dog Tags (30 pcs) – 46mm x 25mm, 1mm Thick, DIY Engraving

What it is

NanTun Rectangle Aluminum Blank Dog Tags are a bulk pack of 30 blank, polished aluminium tags sized 46 mm by 25 mm with a 4 mm hole. Each tag is designed for easy engraving, so you can create personalised pet identity tags, medical notes, or casual ID plates for dogs and cats alike.

Why you might want them

If you value practicality and customisation, these blanks offer a straightforward canvas for DIY engraving. The 1 mm thickness provides a lightweight option that’s still sturdy enough for daily wear, and the smooth edges reduce snagging and sharpness. The mix-colour option in the pack adds a bit of visual variety without needing additional purchases.

What stands out on paper

The key strengths are the clean, burr-free finish and the standard 4 mm hole for easy attachment to collars. The size accommodates short names or numbers, and the aluminium material keeps weight modest while resisting corrosion in normal outdoor use.

Limitations to consider

On the downside, the documentation doesn’t specify coating or anti-tarnish treatment beyond the polished finish, so expect typical aluminium care requirements. For engraving, you’ll need your own tools or a third-party service, no engraving method or equipment is included. If you’re seeking heavy-duty durability or speciality coatings, these blanks may not be ideal.

Ideal use cases

• Personalised pet IDs for dogs and cats
• DIY number plates, address tags, or quick-reference notes
• Temporary or seasonal tags for training, travel, or events In practice, they work best for simple, short inscriptions and casual wear rather than high-security identification.

Who they’re for

• Pet owners who enjoy DIY projects and want to imprint a name or number themselves
• Household using multiple tags for several pets or temporary tagging needs
• Crafters looking for a bulk supply to experiment with engraving techniques They may not be the best option if you need highly durable, long-term identification with robust coatings or compatibility with specific cat/dog collars that require non-standard hole sizes.

Before you buy

• Check the hole diameter (4 mm) and ensure it fits your existing collars or tag rings
• Consider how you’ll engrave: you’ll need a suitable engraving tool or service, as none is supplied
• Think about your storage and care: aluminium can darken subtly over time if exposed to harsh chemicals
• If you prioritise a uniform appearance, note that the pack is described as mix colours, if a single colour is important, plan accordingly

Practical use example

Imagine you’re organising a local pet-day event and you want lightweight, inexpensive IDs for a dozen dogs. You can lightly engrave each tag with a pet’s name and a contact number, thread them onto standard collars, and swap them out as needed. The low weight helps prevent discomfort on active dogs while the process is simple enough for a DIY session at home.

What to compare or consider as alternatives

If you need specialised finishes, stronger coatings, or larger hole sizes, you might compare with other blank tags or consider pre-engraved options. For frequent replacement or high-visibility tagging, a ready-made printed tag could be more convenient, though at a higher price per unit. For casual, low-cost tagging, these NanTun blanks offer a pragmatic balance of size, weight and customisability.

In the box

Final verdict

Is it worth it?

Worth considering if you’re after a bulk supply of affordable, lightweight blanks for basic DIY pet IDs and you’re comfortable with engraving them yourself. They’re best suited for simple inscriptions and everyday use rather than heavy-duty or long-term, high-visibility tagging.
