At present, there is a kind of double-sided tape specially used to stick fake nails silicone on the Internet. It's very cheap, about 4 yuan for two hands.

Stick it firmly without hurting your nails. This is what I used for my last wedding photo. The effect is very good.

The only fly in the ointment is that there will be a little silica gel on the nail surface after use, which looks very black, but it really doesn't hurt the nail. I applied a transparent primer before pasting. After removing fake nails, this primer didn't cost anything.
