Approximately 8cm in diameter, set of 10 (cannot be replaced) Only two layers of double gauze. No interfacing or other materials are inserted inside. Plastic snaps are used. The snaps are placed on the inside to avoid contact with the skin. Reinforcement fabric is used inside the snap area. (Not visible from the outside) ⭐︎I am also selling gauze handkerchiefs. These are made using fabric scraps that are too small for handkerchiefs, so they are offered at a lower price.⭐︎
