This is a part of an old sample book. The material is unclear, but it seems to be primarily cotton mixed with something. It has a smooth texture. It is thin. Authentic retro. The dimensions vary slightly from piece to piece, but the differences are not significant. 23 cm x 34 cm I hope you will transform it into your favorite handmade creation. When sending, I will fold it compactly and send it via regular mail. #HeiseiRetro
