i have just come accross a listing for an ear piercing gun that is advertising it as being designed for noses amd even the tragus,

As a body piercer of 9 years i find  this most disturbing as the ear piercing gun does what it says on the tin, "ears"

an ear piercing gun should not even be used on the top of the ear just the lobe

this particular listing had the studs seperate and not steralised,

if you are looking to by an ear piercing gun the safest and cleanest is proberly the caflon blu system as the parts for the gun come pre packed and steralised in the back of the studs.
