DONT USE A SAFETY PIN LOL
ive done that myself in the past but it can cause bad infections and u wouldnt want your lip amputated would u ?
When being pierced 316L surgical stainless steel must be used.I use cathiter needles they are the most sterile and best and single use but a little bit more expensive.If i was you i would try and get your hands on one of them.You can also get those curved things and use a cork (i dont like that at all) tattooists pierce that way its not the right way but will get the job done.Make sure that you align it properley too as if its uneven it will never heal properley.Lip is so sexy i want mine done but in still thinking about it.I do have a few though and some i did myself but after i was qualified lol.
