Thank you for viewing! This is a set of 3 lace fabric 3D masks. :) The mask on the right is made of thin fabric, while the other two are made of thick chambray 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 the mask wrinkles after washing, we recommend ironing it. This will allow you to use it beautifully 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.
