The RIZE.. Swich is loaded with fun. This versatile pocket stroker is self-lubricating, just add a little water or saliva, and everything gets slippery. Plus, it glows in the dark - easy to see at night, alone or with a partner. Swich is double-sided and reversible: choose between ribs for sensational stroking or pressure point massage. Super-soft and flexible, easy to clean, it fits most shaft sizes and is free of phthalates, fragrances, paraffins, and latex.
