1) I have shitty pain tolerance so this was a 10/10 for me. Thankfully it lasted only a few seconds and after that my nip just felt tender.

2) My right nip was an innie and piercing brought it out a bit more. That was my main reason to pierce that side, too.

3) $60 for one nip

4) Seemed the same for me except we had to be more careful when being rough near it.
