Great for patch hat pressing, no discoloring or marking during transfer
Number of Items: 6
Bought to hold my leather patches down while pressing them to hats, and they work great. They have not left any residue or discoloring when pressing hats, even with white patches. Very happy with how these perform and would recommend to others who make patch hats.
