This is a custom Battle Beaver PS4 controller. It has three rear buttons on the left side, with X, Triangle, and Square from top to bottom. The cable port has been changed to a Type-C cable. Otherwise, it's the same as a standard controller. The right stick feels a little stiff, so I'm selling it at a lower price. Feel free to try out the feel. Operation confirmed. Instant purchase available. It will be waterproofed and shipped via Mercari shipping in a Yu-Packet Plus box with cushioning material. 27
