I did a google image search to see what this staple looked like... I couldnt find much but from what I did find... I have piercings in the same places people are putting staples and let me tell you that it made no difference my weight loss. I know all about piercings... and IMO this ear stapling is a joke and sounds VERY dangerous. If you want something cool in your ear - go see a TRAINED piecer and I am not talking the little shop in the mall with an ear gun
I don't know exactly how these staples work but from what I can tell they use something simlar to a 'stapler' or rather a piercing gun... very very dangerous! They put way too much pressure on your ear and can be VERY harmful and cause A LOT of damage. Also they can not be cleaned properly and can transfer dieases. Also - again I do not know EXACTLY how they work - but the staple looks tight and when forcing metal through your ear (or any body part for that matter) you have to leave LOTS of room for your body to swell, etc. Enough of my rant.
Anyway that is my 2cents
Please don't do it!
