This is a set of two M-size "Aqua Titanium Boxer Briefs" from Phiten. These are boxer briefs with an open fly. "Aqua Titanium" is Phiten's water-soluble metal technology, which disperses titanium in water at the nano level. This Phiten technology allows titanium to permeate each individual fiber. By wearing products using this technology, it supports the mind and body to return to their natural state of relaxation. This can also be expected to help loosen muscles. (Aqua Titanium is a brand of water-soluble metal technology developed by Phiten.) Aqua Titanium is impregnated in some parts of this product. This product is unused and unworn.
