4-Layer Structure 3D Mask Child Size, 29 pieces (Individually Wrapped) I purchased a box of 30, but after opening one to try it, the size was too small, so I am selling the remaining masks. I took photos and packaged them immediately after opening the original packaging. Since they are individually wrapped, I believe they are hygienic, but please refrain from purchasing if you are concerned. The 29 masks are packaged as shown in images 15 and 16, taken out of the box. The box will also be included.
