The SPINNER integrates a new technology that offers functional advantages. A coil embedded in the elastomer cover gives it its unmistakable appearance and widens when inserted. During use, contraction and expansion of the coil alternate, creating an automatic rotation. Three different versions of the nobby textures inside are available. They have been fine-tuned to optimise the airflow from inside upon insertion. After washing, the product, whose fresh, unusual design is intended to give a positive feeling, can be dried in the packaging.
