Leather Locking Pins 

These small brass pins are incredibly useful for temporarily holding leather pieces together prior to stitching, facilitating alignment of stitch holes with or without adhesive. They come in two lengths, 12mm and 18mm, and are sold in packs of 5 or 10.

The 12mm pins are ideal for leather thicknesses ranging from 1-6mm, while the 18mm pins are better suited for leather between 6-12mm thick.

Instructions: Before removing or inserting the pins, ensure to pull out the lock mechanism located at the bottom of the brass component.
