like everything anything can break but you can bend them and they don't break easy,, i have the flexible lip ring and they last me a long time and i also bite and play with it so i think it should be fine
I'm debating on this very highly lol. My nose I totally feel I could do myself, but I may get these and wait til I have the $$ to get my belly done and my nose piercing professionally just to be safe. Cuz knowing my luck I'd screw up what gauge and so on and so forth lol.
