Thank you for viewing! This is a set of 3 three-dimensional masks. (^^) The one on the left is made of linen fabric. Size (when folded in half): Length: 12.5 cm Width: 11 cm The lining uses medical-grade cotton fabric sold at drugstores. The elastic is threaded through, so please adjust the length and tie it to fit. (^^) If wrinkles appear after washing, ironing is recommended. This will allow you to use them for a long time and keep them looking nice. These are handmade, so there may be some imperfections, but we appreciate your understanding. m(_ _)m We also offer discounts for multiple purchases, so please feel free to comment if you're interested.
