The Fun Factory FOU (pronounced “foo”) is a multi-purpose vibrator made of high-quality silicone and plastic. Its innovative design encourages you to use your imagination while you pleasure yourself or your partner. It’s a very unobtrusive toy and would work well for anyone who needs to be discreet with their toys, or is looking to introduce toys into couple’s play. Quiet and body safe, Fou promises a lot, and delivers on much of it. Rechargeable and completely waterproof, Fou packs a moderate punch in an interesting package.
