Needle Forceps 5" long with 4mm Jaws These are perfect for inserting dermals. Reason being is these will only grab the top of the anchor. Unlike the Micro Dermal Tool that is diamond shaped, these tools don't touch the anchor. Only the gem/disc top is touched, thus making it easier to insert. These are good for holding needles, or anything that is bigger then 4mm wide. So if you have a 5mm ball this is good, if you have a 4mm disc or 4mm ball, this is not good a 4.4mm disc is good.
