This is designed and made by myself in England; listing include one stamp jig in black reinforced plastic, no stamps or other item included.

Recommendation on use: do some trial tests on a test surface to familiarize yourself with the methods. The magnets are there to simplify the location on the parts. I do recommend to lock the jig via zip ties, tape or via a clamp, to hold it in place firmly. suggestion is to mark with a pencil the hedge of the jig in case of unwanted movement.
