Nishikawa [Air] Air Portable Cushion 40x40cm (S size) Uneven Structure, Distributes Body Pressure, Reduces Fatigue Even After Sitting for Long Periods, Breathable, Air AiR Blue HG90601662B I purchased this new, but I'm selling it because it doesn't fit the height of my desk. I only tried it for a short time, but there's a spot where a thread seems to be slightly loose, so please check the photos. I will package it in a simple manner, with water protection and cardboard reinforcement. Please note that I will not fold the cushion. Please check the accessories (bag, tags) in the images. *Since this is a personal inspection, I cannot guarantee perfection. There are no receipts, proof of purchase, or warranty. Please be aware of this, and please purchase after confirming the photos and agreeing to the condition.
