Tokyo Nishikawa Bincho Charcoal Air Cell Straw Pipe Pillow Refill Approximately 300g Size of one bead: Approximately 5mm x 3mm (actual size) I purchased this as a refill when I had a custom-made pillow made at Tokyo Nishikawa, but I have kept it stored without using it. I will send it in a zippered plastic bag. Please consider purchasing if you understand that this is a household item. I will ship it anonymously via Rakuraku Mercari. There are no smokers in my family, and I do not have any pets. Instant purchase is OK. #Nishikawa #AirCell #PillowBeads #JibunMakura #JibunMakura
