Review (1/5): Absolute garbage.
Even at the price I paid, these aren't worth the money. I was duped into buying them by the amount of stars they had, but I should have actually gone and read the reviews. There are none.
I purchased these to try extending my natural nails with structure gel. These things do not stuck together when trying to pinch to make the form, much less stick to the skin to anchor it to the finger.
I couldn't get it to sit flush underneath the nail, even after working with it for close to 15 minutes. So there was a gap between the form and the bottom of the nail when I began trying to do the structure gel. It made the nail tip I created too thick and I ended up having to file it, which would have been just mildly annoying if I had a nail drill. My nail drill is out of commission, which is why I bought the forms to begin with, rather than do a polygel dual form.
