KAM plastic snaps are industrial grade so are intended to have a strong closure. The thinner the material, the more difficult it will feel to open the snaps, and it may feel like your fabric is at risk of tearing.
For that reason, we recommend reinforcing thin, stretchy, or delicate material with a sturdier fabric prior to installing the snap. Size 16 plastic snaps can also be used in lieu of the more common size 20 because they are smaller and have a gentler grip.
If you have already attached your snap to your project, opening and closing the snap several times will help to loosen it just a bit. It's also be suggested by some of our Facebook group members that rubbing wax / beeswax / zipper glide sticks on the snaps can help.
