Have to be honest and say that after purchasing 7 or 8 pieces of 316 Stainless piercing jewelry from this vendor, this one didn't meet my expectations ... why?  the ball is too loose once set in place. Problem is when wearing it, there is a very good chance the ball can become dislodged and fall out of my pant/shorts or worse yet, fall into a urinal (PA piercing). I did contact Scrap Metal 23 and asked for a replacement. They were accommodating, asking that I return the defect piece first. I chose not to go thru the return process, in favor of trying to use a pair of closing pliers to see if the gap could be reduced in order to tighten the ball in place. Will advise once I try it ... but a 0 guage is one thick piece of metal to bend.
