There's no mechanism. You give it a gentle twist and it pops on. So there has to be flexibility. I don't want to sleep with it because it seems obvious that a nail design would catch on something -- whether small or regular size.
It shouldn't catch , i mean I might squash it with my body weight
Would bending it every night not warp and weaken it ?
I actually really think it's so beautiful but nervous to buy something that will just break.
In honestly i want to be convinced it's a good purchase as i'd love to layer one with a vca sweet lile i have seen others do
