Deep Engraving Without Black Infill

These 25mm brass number tags provide a compact metal option for identifying keys, lockers, equipment and other numbered items. The characters are engraved approximately 0.3–0.5mm into the brass and left unfilled, giving the tag a simple natural-metal appearance.

Ordering Your Numbers

Enter the numbers required in the engraving box and add the total number of physical tags to the basket. Numbers do not need to be consecutive, so individual replacements and mixed sequences can also be ordered.

For example, if you require two sets numbered 1–10, enter this in the engraving instructions and add a quantity of 20 tags to the basket.

Deep Engraved or Black Filled?

This version has deep engraving with no colour added to the recessed characters, giving a more understated natural-brass appearance.

If you want the numbers to stand out more strongly against the metal, choose the 25mm black-filled version instead.

Please Note

Brass is a natural metal and its appearance may gradually change through handling and environmental exposure.

Split rings and ball chains are optional accessories and are supplied separately when selected.
