This is the Bauhutte BC-300G (Delta) gaming cushion. The color is black. I was using it with a work chair, but the triangular shape, which is a feature designed to correct posture, didn't quite fit my body, so I'm putting it up for sale. There are no noticeable stains, but there is some wear and tear, so I've listed it as "slightly used". Please check the photos carefully and understand that this is a used item before purchasing. Please refrain from bidding if you do not intend to purchase, as it may cause inconvenience to others. ○ Official product page (for reference) https://www.bauhutte.jp/product/bc300g/ #gaming #game #cushion #eSports #work #workchair #zabuton (floor cushion) #Bauhutte #Bauhutte #posturecorrection
