Will your ears grow back after 00 plugs?

No. You will be stuck with great gaping holes in your ears and it will take a long time for them to shrink but they will not "grow back".

YES. whoever answered your question before doesn't know what they're talking about. I and many of my friends have stretched ears and i've seen people who've had their ears stretched to half inch and still healed all the way. not saying you won't be able to notice some scarring but they will definitely heal up! :)
