Lofty Sleep Pillow No. 2, Rigid Charcoal Pipes I believe I purchased this for around 28,000 yen. I haven't adjusted the amount of pipes from the standard No. 2 size, but I have washed it at home many times, so it may have worn down somewhat. 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. It's not new, but would anyone interested in trying it out, just the contents, or just the unit cover like to get a good deal? ^_^
