Dave,,,the durability feels like rubber,,,only downsides are expensive, and really thick if you get too much on it, a d really freaking la a hot if you get that hot rubber stuck on your fingers,,,,,but you don’t have to bake then once done,,, just need to be quick to place those eyes before it cools too fast,,, once it’s done right,,, you can take a hammer to these bad boys and they won’t fall apart, chip or flake like regular powder,, In my book,,, that’s a win!
