AOKI Washable Masks - 5 masks in a pack. Although the pack has been opened, I'll include an extra mask of the same type as a bonus. There are a total of 6 masks, all unused. When shipping, I will put the bonus mask in the bag of the 5 washable masks, and I will open the bag once for shipping, so please be aware of this. Shipping will be via either Yu-Yu Mercari Bin or Kurakara Mercari Bin.
