Shimamura mumu UV cut 2D Wide Mask 15 sheets I'm selling 15 unopened sheets because I bought a 30-sheet pack (15 sheets x 2) and found one to be too big. These were very popular on Instagram. I'm selling the unopened ones, so I think the hygiene is fine, but please refrain from purchasing if you are concerned. The masks (15 sheets) will be shipped only. Please note that the box is not included. No price reduction.
