About Willy Molding Kits

Willy molding kits from Clone-a-Willy and Empire Laboratories Inc. turn anatomy into a custom keepsake using medical-grade alginate and body-safe silicone. The process is straightforward: mix the moulding powder with water, maintain firmness during the short set time, then pour platinum-cured silicone into the mould. Kits range from seventeen to seventy-two dollars and include everything needed for one casting—moulding powder, silicone, a mixing container, and step-by-step instructions.

Decide whether you want a vibrating or non-vibrating result. Vibrating kits such as the Clone-A-Willy DIY Vibrating Dildo Kit Light Skin Tone or Clone-A-Willy DIY Vibrating Dildo Kit Glow-in-the-Dark include a waterproof bullet vibe and hollow core, adding sensation to the finished piece. If you prefer a solid replica, the Clone-A-Willy Plus with Balls Medium Skin Tone captures testicles alongside the shaft for fuller anatomical detail. Refill silicone—like the Clone-A-Willy Silicone Refill Medium Skin Tone or Clone-A-Willy Silicone Refill Neon Purple—lets you re-cast from the same mould or experiment with different colours without buying an entirely new kit.

Colour options span realistic skin tones—light, medium, deep—and playful shades including neon purple, jet black, hot pink, and glow-in-the-dark blue or standard glow. Choose a tone that matches your skin, your partner's preference, or your aesthetic whim. All silicone in these kits is body-safe and non-porous, so the finished replica cleans easily with soap and water or toy cleaner and works with any water-based lubricant.

Timing matters: alginate sets in roughly two minutes, so read instructions fully before mixing and have a partner or mirror handy if you are casting yourself. Store leftover silicone and moulding powder in a cool, dry place; sealed refills stay viable for future projects. If your first attempt does not capture every detail, refill packs and extra Clone-A-Willy Molding Powder mean you can try again without starting from scratch.

Frequently asked

What is included in a willy molding kit?
Each kit contains medical-grade alginate moulding powder, body-safe platinum-cured silicone, a mixing container, a moulding tube, and illustrated instructions. Vibrating kits also include a waterproof bullet vibrator. Refill packs supply additional silicone or moulding powder for repeat castings.
How long does the moulding process take?
Mixing and inserting into the alginate takes about two minutes before the mould sets. The silicone cures in roughly twenty-four hours. Total hands-on time is under ten minutes; the rest is waiting for the material to firm.
Can I make multiple copies from one mould?
Alginate moulds are single-use—they tear when you remove the casting. To create another replica, you will need fresh moulding powder. You can buy refill silicone to pour into a new mould or try a different colour without purchasing a full kit again.
Are these kits body-safe?
Yes. The silicone is platinum-cured, non-porous, hypoallergenic, and phthalate-free. Alginate is the same material dentists use for dental impressions. Both are safe for skin contact and easy to clean with mild soap and water.
What if I am not firm enough during moulding?
Firmness is essential for capturing detail. Work in a comfortable, private setting and consider involving a partner for help or encouragement. Some people take a vaso-dilating supplement beforehand, but always follow product guidelines and listen to your body.
Do vibrating kits require batteries?
Vibrating kits include a battery-powered bullet vibe. Check the individual product listing for battery type—most use watch batteries or AAA cells. The bullet is removable, so you can replace batteries and use the replica with or without vibration.
