Can KAM Presses be Used for Leather?

KAMsnaps® presses work the same regardless of what material they're pressing through.  It's the fasteners themselves that matter more.  As long as the appropriate fastener length is used for the thickness of your particular application, then you shouldn't have any problem.

(Please note that our dies are custom molded to work with the fasteners we carry and may or may not work with those from other sources.)
