Before removing from backing, condition your stamps with very fine sandpaper, scuff the surface in two directions. This helps the mediums stay put, and not bead (which some types, like ceramics glazes, tend to do).
Remove stamps from backing when ready to use. This takes some force, but don’t worry, the stamps are strong.
Can be easily cleaned with mild soap and water and reused over and over again!
