Lofty Sleep Pillow No. 2, Rigid Charcoal Pipes I believe I purchased this for around 28,000 yen. While I haven't adjusted the amount of pipes from the standard No. 2 size, I have washed it at home many times, so there may be some wear and tear. There are no noticeable stains or tears, but please understand that this is a used item before purchasing. I have washed it at home according to the instructions on the label.
