This is a scrunchie made using Liberty Tana Lawn fabric. It comes as a set of 2. The size is approximately 5cm in diameter for the inner diameter and 11cm for the outer diameter. It's large enough to fit loosely around an adult's wrist. Suitable for children and adults. Japanese-made elastic is used, so it's designed to be durable and long-lasting. However, there is a 1cm opening in the seam to allow for elastic replacement.
