Embossing plates for Sizzix Bigshot or similar. They are not suitable for thinner stock as they partially cut it in addition to embossing. The plates are a little thick but seem to work. You could thin them up by pushing them into your build plate. I printed in PLA with 5 top and bottom layers at 100% infill. I wouldn't expect to get to many runs out of them. Tape them together in a clamshell to maintain alignment. The printing process leaves artifacts that were more prominent on the negative side than the positive side.
