Skin anchor with gem-20%

Skin anchors are almost like dermal anchors, except that the top of skin anchors or divers cannot be interchanged, while the top of dermal anchors can.

This skin anchor has a diameter of 1/8" (3 mm), both on the top and the bottom plates. The distance between them is 1/16" (2 mm), and the gauge size is 16g (1.2 mm). You can choose the gem color you prefer. 

It's made of solid titanium and comes in a single piece, so there's no risk of losing the top.
