Design your own sex toy as a couples experience

The Clone-a-Willy kit turns casting into an event. Mix the algae-based molding powder, insert, wait — and in minutes you’re holding a vibrating silicone replica with lifelike detail your partner will recognize. The glow-in-the-dark blue silicone adds a playful visual buzz that makes the finished toy feel genuinely special. Clean the finished replica with warm water and a gentle toy cleaner to keep it in great shape. Explore more ideas in our Couples Pleasure pillar guide.
