A monochrome long boxer undie set in two colors: low-key black and pure white. The glossy waistband makes the waistline more outstanding. The pants are longer, less slippery, and tighter.

The folds on the side of the pouch form a three-dimensional bag-like design, allowing you to place your treasure’s parts downwards. The masculine feeling of your big stuffs protruding forward and swinging pipping from side to side with your steps greatly highlights your masculinity.

The transparent and delicate fabric that is close to the natural color of your skin gives you a classic and elegant wearing experience.
Try your best to show off your true qualities, GX3【PRIME SKIN】collection.
