These are vegetable tanned leather patches. These patches are 3"x2". These patches have a sewn boarder around the edge. These patches have been confirmed to be real leather and vegetable tanned by both the burn and boil tests.

Patches with a heat activated adhesive applied and 3m 300LSE adhesive are also available. The 3m 300LSE adhesive is a pre-applied adhesive ready to use on any surface. The 3m does not require heat to set the patch, it works more like a pre-applied super glue.
