OwnMy 36PCS Leather Stamping Kit, Capital Letters and Numbers Stamps Set, 1/4 Inch 6mm Alphabet Stamp Leather Stamping Tools Review (2026)

Updated September 14, 2026 · Research-based review

Our verdict

OwnMy's 36 piece stamping kit gives 26 capital letters and 10 numbers at a 6mm, 1/4 inch letter height, sized for wallets, key fobs and other small personalized goods. The alloy steel stamps hold up to repeat use, but the small letter face means loose stamps need careful spacing and are not the pick for bold text on wide belts.

What this kit covers

This set includes 36 individual stamps, made up of the 26 capital letters plus digits zero through nine, so it covers names, initials and dates without needing a separate number set. Each stamp head measures roughly 10mm by 8mm by 14mm with a letter face of 6mm, or about 1/4 inch, and an overall stamp length near 98mm, close to 3 and 7/8 inches. That size sits at the small end of the common alphabet stamp range, which makes it a good match for compact items like wallets, key fobs, luggage tags and watch straps where a larger letter would look out of proportion against the rest of the piece.

Materials and build

The stamp heads are made from alloy steel, which the maker positions as strong enough for repeated mallet strikes without the letter face deforming over time. Because the stamps are loose individual pieces rather than a fixed strip, each letter needs to be picked up, aligned and struck on its own, which is standard for kits at this size and price point but does mean straight, evenly spaced text takes more care than a one piece name plate stamp. A spacing guide, ruler or piece of masking tape as a guideline helps keep letters level across a line of text, especially on longer names or dates with several characters.

Getting a clean impression

The maker specifies this kit for genuine vegetable tanned leather, with the leather surface dampened and left slightly soft before stamping for the cleanest impression. Working on a hard, flat surface, such as a metal plate or rubber cutting mat, under the leather gives the mallet strike something firm to press against, which matters more with loose alphabet stamps than with a single decorative stamp since every letter needs a consistent strike depth to look uniform. The kit is not intended for metal or wood stamping despite being metal stamps, since it is built around the give of dampened leather rather than a rigid surface.

Where it falls short of bigger stamps

Against the Tandy Leather Craftool Sheridan alphabet set, which uses 1/2 inch letters, this OwnMy kit reads noticeably smaller once stamped, so it will look faint or understated on a thick belt or larger bag where a bolder mark is expected. It sits closer in size to similar 36 piece, 6mm kits like the JONMON letter and number set, and slightly smaller than 37 piece 6mm alternatives on the market. For small leather goods specifically, the compact size is an advantage rather than a limitation, since it leaves enough blank leather around the text to look intentional rather than cramped.

Who should buy this size

This kit suits makers personalizing wallets, key fobs, small pouches and straps who want clean, legible capital letters and numbers without a stamp overwhelming the piece, matching our score of 8.4 out of 10 for fit and value. Anyone planning to mark wider belts, larger bags or items where a bold, easily readable stamp from a distance matters should look at a 1/2 inch set like the Tandy Sheridan alphabet instead. For its intended scale, the 36 piece kit delivers a complete letter and number range in alloy steel that holds up to regular use.
