Please read the whole description! A vegan alternative to bone folders. Each one is unique in pattern and may vary slightly in length. Made of high quality acetate. Since acetate is a softer material than bone, it is suitable for folding lighter weight papers like writing and sketch paper but not for heavier papers like watercolour paper and cardstock. Slightly flexible, yet strong and durable. The glossy finish will rub with use. Does not leave residue on paper. ~details~ 5.75” long x 1.0” wide, 3/16” thick 14.5 cm long x 2.5 cm wide, 5 mm thick Rinse to clean, can use soap if needed
