I've created a thin case without interfacing for easy washing. It's also convenient to carry in your bag. The fabric has been pre-washed. Size: Width (longest) 26cm Height 14cm (Sample mask 1 is 17 x 9.5cm) (Slight variations may occur.) Plastic snap (May damage the fabric if opened and closed too forcefully.) Outer and lining: Cotton (The finish varies depending on the fabric thickness.) Outer fabric: Liberty fabric Each item is carefully handmade, so there may be some imperfections such as distortion or misalignment. Please refrain from purchasing if you are concerned. #maskcase #maskstoragecase #maskstorage #handmade #portablemaskcase #maskstorage #temporarymaskcase #kid'smaskcase #schoollunchmaskcase Type: Mask cover
