I discovered these finger protectors over the summer. They come in packages of 32 or more, and you can get them cheaply at supermarkets and pharmacies.
They’re designed to protect injuries on the fingertips and in that immediate area without being cumbersome. If you are a nail-biter or a cuticle-picker, this is great news.
These finger protectors are also excellent for preventing you from picking, if you tend to use primarily your fingernails (which I do). They also make it harder to feel for imperfections on your skin.
Since they’re rubbery, they’re also fun to fidget with.
Cheap, widely available, and with many uses, these are really excellent tools.
