Some products you buy. This one you make — from scratch, in your own home, using your own body. The Cloneboy Cast Your Own Silicone Dildo Kit turns any erect penis into a bespoke silicone replica complete with suction cup base. It’s a gift, a keepsake, a long-distance solution or simply a novelty with real staying power.
Everything Included, Nothing Assumed
The kit contains all materials needed for one full casting: medically tested alginate moulding gel made from natural algae (skin-safe and non-irritating), liquid silicone for the final cast, mixing containers, a suction cup insert, and detailed instructions. A lasso-style cock ring is provided to maintain erection during the three-minute setting window. Once demoulded and cured, the finished dildo is yours to keep — body-safe, flexible and usable with or without harness.
How It Works
Mix the alginate powder with warm water, pour into the tube, insert the erect penis and wait three minutes for the gel to set. Remove carefully, pour the liquid silicone into the cavity, insert the suction cup and leave to cure overnight. Demould the following day and you have a detailed, flexible replica ready for use. The process is straightforward — no kiln, no specialist equipment, no prior experience required.
Why Clone a Penis
Popular as a surprise gift for long-distance partners or as a novelty between couples who want something genuinely unique. Some people cast themselves as a keepsake; others commission a partner’s anatomy for solo use. Either way, the finished product is a proper silicone dildo — not a gimmick that falls apart after one wash.
