A set of versatile fabric and mask stoppers. - Sizes: 50cm x 66cm - Sizes: 48cm x 100cm - Sizes: 35cm x 110cm - Included: Rubber bands - Included: Mask stoppers Thank you for looking. I bought these intending to make masks, but I'm not going to, so I'm selling them. All the fabric has been pre-washed and ironed. The gauze fabric is off-white, not pure white. If you are planning to make masks, you may want to wash them again. The rubber bands are apparently for masks as well. I hope someone can make good use of these.
