This mask is listed as size M, but I think it's for people with smaller faces. I'd like to sell it to someone with a small face, or someone who has used it before. Of course, anyone who wants to try it is welcome too(^^) It's a cute mask. This is a new, unopened set of 12 masks x 4 sets of the GREIGE/CHOCOLA BICOGAO mask. - Brand: sokaiteki - Model name: BICOGAO - Colors: GREIGE/CHOCOLA - Size: M (18cm x 9cm) - Quantity: 12 masks x 4 sets - Condition: New Thank you for looking. *Please note that I will ship the masks without the box due to shipping constraints. m(_ _)m I can ship with the box if you purchase 2 boxes! I will charge 450 yen for this, so please comment if you'd like this option.
