Unused, purchased at the beginning of this year. Set includes: White x Light Gray String x 4 Light Beige x Wine Red String x 1 PM2.5 compatible. I wanted 5 white ones, but they were out of stock, so I included light beige, which blends well with the skin. The bags are sealed with a zipper, not the type that needs to be cut open. Please refrain from purchasing if this is a concern. There are some with traces of sticker removal. The outer bags may have some wrinkles, please understand. Due to the tight packaging, I cannot combine it with other masks. I will apply a little pressure to fit it in the post. I won't use excessive force that would crush them, but there is a possibility of marks. ※【I will use the delivery vinyl bag in the photo. For cost reasons, the masks will be directly sealed inside. Please understand.】 - Color: White masks and beige masks - Size: Regular size - Quantity: Set of 4 with 10 masks each - Function: PM2.5 compatible - Brand: MASCLUB
