Japanese masking tape, also known as Washi tape, is a wonderfully versatile craft product. I cannot imagine life without it. Use it to embellish packages and envelopes, create collages, make labels, decorate vases, boxes, or picture frames — the possibilities are endless.Dimensions: 15 mm (about 1/2") or 9 mm (about 1/4") wide x 15 m (about 50') long. 10 rolls.
