Sumikko Gurashi Children's 3D Mask Soft, flat elastic material that is gentle on the ears Three-layer structure For ages 4 and up New, 10 masks + new, 7 masks ⚠︎ The package of 7 masks has been opened, but they are new and unused. I mistakenly thought the package of 10 masks was opened, so I opened it once, but all masks are new and unused. They have been stored in a sealed container. Please purchase only if you understand this.
