The apple embroidery is adorned with Swarovski crystals, giving it a sparkling look that's popular with children. The width of the thread is short to prevent it from catching on a child's fingernails when tying their own hair, and the stitches are finely sewn using a technique called "tatamise" stitching. There's also a secret to the elastics: three elastics are wrapped inside the fabric, making them resistant to tearing, deformation, and durability.
