Unopened and unused, purchased at the beginning of this year. Ice Gray x Black String 3D mask. Ice Gray is almost gray with a slight hint of blue. I think it's a beautiful color. PM2.5 compatible, a set of 5 packs with 10 masks each. The bags are sealed with a zipper, not the type that needs to be cut open. If you are concerned about this, it's best to refrain from purchasing. There are some with traces of sticker removal. The outer bags have some wrinkles, but please understand. Different packages are included. The color of the bags is different, but the color of the contents is the same. - Color: Ice Gray - Size: Regular - Quantity: 5 sets of 10 masks each - Function: PM2.5 compatible - Brand: MASCLUB
