Thank you for viewing! (✿︎´ ꒳ ` ) This is a set of 5 foaming nets specifically for the "Zen Yokasekken" soap made by Chojuno Sato, which produces hydrogen-infused foam! I'm not very familiar with hydrogen-based health devices, so I'm not sure about the effects, but using this net makes it easy and fun to create fluffy, bouncy foam ଘ(੭ˊ꒳​ˋ)੭✧ Brand new, unused, and stored at home for a long time. Please refrain from purchasing if you are concerned. m(_ _)m I have a subscription, but I use it so slowly that I can't use up my stock, so I'm selling the accumulated nets together. For those considering trying it out, or those just looking for the net, How about it? If you purchase with other items, you will receive 10% off the total price♪ Feel free to ask! (＾∇＾) Please feel free to comment if you have any other questions. Type: Soap
