The protrusions located on the exterior surface of the container are configured to make contact with, and soften, clothing during the drying cycles by gently "massaging" the fibers.
Additionally, the protrusions are designed to gently separate the cloths during the drying cycles for increased air circulation, which results in faster drying times and energy savings. These actions may also reduce wrinkles and lint in the dryer and reduce ironing outside to the dryer.
