Wait for 10-15 working days. ▪️ The outer layer is imported from Japan, the United States and South Korea, and the inner layer is a random pattern of Japanese double yarn or Korean plain organic cotton. (This kind of combination is that we don't think it is difficult to breathe and the part that touches the face is very comfortable) 🌟We have reduced the size of the mask so that the mask behind the mask will not look too big when worn, and the opening next to the mask will not be too large. After receiving it, it is normal to look as large as the mask. Fold it After inserting it, it will become normal after opening the zipper.
