I am selling these masks because my child no longer uses them. I opened the package to check the number of masks, but I was careful not to touch the masks themselves. Please refrain from purchasing if you are concerned, as these are not individually wrapped and have been stored at home by a private seller. - Quantity: 6 masks (pink) - Quantity: 2 masks (blue) - Size: 145mm x 95mm - Intended Use: Virus protection, house dust - Manufacturer: Yui Co., Ltd. Thank you for looking.
