Be cool. Tough and refined. Make a border or a pattern or pair with other bike related stamps. I see this one being versatile. :)

Three sizes - may differ ever so slightly as I make them special for you.
Choose:
Large on 1/2” round, design actual 4.4x11.5mm
Medium on 3/8” round, design actual 3.4x8.8mm
Small on 1/4” round, design actual 2.3x6mm
A full set at a discount.
Shanks all a bit less than 3" long.

In my examples, I patina and then polish away the excess, leaving patina at the edges, which gives the appearance of an outline.

Fully hardened and then tempered tool steel, batch tested and verified.
Only for the stamps mentioned- others in pic not included.
