I'm wondering if anyone could suggest a stress toy for compulsive skin picking. I've been browsing a few shops online but there's so many types of fidget toys and I'm sure I'm looking for something pretty specific.
The closest thing I could find is those stress balls that have a second layer that pops out of holes on it. My dermatillomania mostly focuses on pimples and it's a unique sensation, the give and then the "pop". Seeing something come out is a big part of the satisfaction I derive from it, so that kind of stress ball seems a step in the right direction.

Has anyone had success using a specific toy to curb the impulse to pick?
