Review (1/5): Cheap Fake Junk
1) These things are so thin that you need 9 to practice on before you can maybe pull the 10th off the back successfully.
2) Directions say to apply for 10 minutes, but even when applied overnight it absorbs nothing. No discoloration of the patch, so probably not even an actual hydrocolloid.
3) Adhesive is painfully strong to remove.
