AMC Paper Textures require the use of Aussie Magic Lube, make sure you order yours!
These are paper textures and can be used with metal clay or with a rolling machine (for sheet metal).  With Metal Clay, I am at 15 uses and still going strong.  For sheet metal in a rolling mill, because you are compressing the patterns with high force you will yield a LOT less usage compared to metal clay.

These laser cut paper textures are great for metal clay.  These are not like your typical rubber texture mats and will take a little getting used to.  Once you get the hang of it, you will love them!
