Thank you for viewing! This is a set of 3 lace fabric 3D masks (^^) Size (when folded in half) Height: 12.5 cm Width: 11 cm The lining uses medical-grade cotton fabric sold at drugstores. The elastic is already threaded, so please adjust the length and tie it to fit. (^^) If the mask wrinkles after washing, ironing is recommended. This will help you keep it looking beautiful for a long time. These are handmade, so there may be some imperfections, but we appreciate your understanding. m(_ _)m We also offer a discount for multiple purchases, so please feel free to comment if you're interested.
