I recommend Ohora gel nails, this month's keyword.

My nails are weak, break easily, and are thin, so it is difficult to go around with bare hands; I have been wearing Ohora stickers for two years now.

It doesn't damage the nails much and is thick, so it is good to use.

I tend to buy several and just choose a color to stick various things on.

The one I put on my thumb is for a pedicure, but I cut it to size and am using it on my fingernails. My nail beds are long and wide, so regular tips are a bit awkward to fit, but Oho comes in various sizes, so if you buy one, you can use it about 2 to 3 times.
