Clone-A-Willy DIY Vibrating Dildo Kit Light Skin Tone

The Clone-A-Willy kit lets you make an exact, vibrating silicone copy of a penis at home. You make a quick mold with seaweed-based powder, fill it with body-safe platinum-cure silicone, set the included vibrator inside, and the next day you have a one-of-a-kind dildo in a light skin tone.

It’s a popular gift for long-distance couples, a fun night in, or just the most personal toy you’ll ever own. The Clone-A-Willy kit captures every vein, curve and detail, and the finished silicone is non-porous, washable and won’t shrink over time.

1. Set up. Work on a non-porous surface like tile in the kitchen or bathroom, and read the instructions first.
2. Cut the tube to match the erect length. If you’re curved, cut it at the curve and tape the pieces at an angle.
3. Make the mold. Mix the molding powder with water as directed, pour it into the tube, insert the erect penis and hold still for about 60 to 90 seconds. You can pull out right away.
4. Pour the silicone. Mix the two parts in a disposable cup with the stir sticks, pour it into the mold and set the vibrator in place.
5. Let it cure overnight, then peel away the mold to reveal your replica.

• Staying hard for the minute it takes is the most common challenge. A partner or a cock ring helps.
• Remove piercings first. Uncircumcised is no problem; whatever goes in comes out.
• Trim long hair or rub in a little petroleum jelly so it doesn’t catch.
• Grab a spare bag of Clone-A-Willy molding powder in case the first mold doesn’t come out right.
• Never touch uncured silicone with bare hands. Clean it off skin with 99% isopropyl alcohol, then soap and water.

The Clone-A-Willy kit is a fun project, but it isn’t a grab-and-go toy.

We carry the Clone-A-Willy vibrating kit in three colors. They work the same way; only the silicone color changes.

• Wash the finished replica with warm water and mild soap or a toy cleaner, keeping water away from the vibrator controls.
• Let it dry fully before storing.
• Use a water-based lube. Silicone lube can damage silicone toys.
• Used alginate is compostable, but don’t wash large amounts down the drain. It can clog pipes.

How does the Clone-A-Willy kit work?

First you make a negative mold: mix the seaweed-based molding powder with water in the tube, insert the erect penis and hold for about 60 to 90 seconds. Then you mix the two-part silicone, pour it into the mold, set the vibrator in place and leave it to cure overnight.

What size penis does the Clone-A-Willy kit fit?

The kit comes with a 10 x 1.5 inch tube that you cut to length. The maker says most sizes work with the standard kit. If you’re about 8 to 9 inches or longer, or thicker than average, you may need the XL vibrator and extra silicone.

What if I can’t stay hard long enough?

You only need to stay erect for about a minute while the mold sets. Clone-A-Willy suggests having a partner help keep things going, or using a cock ring. If the first mold doesn’t work, you can buy extra molding powder and try again.

Can I make it without the vibrator?

Clone-A-Willy designs the silicone kit to be used with the included vibrator, because the vibrator takes up space in the mold. Without it you’d need extra silicone.

Will it copy every detail?

Yes. The molding powder is the same kind of material dentists use for impressions, so veins, curves and foreskin all come through. Remove any piercings before molding.

What if I’m curved?

Cut the tube at an angle where your curve is, turn the two pieces to match the angle and tape them together with duct tape before you start.

Do I need to shave?

No. Hair usually isn’t a problem. If it’s long, trim it or rub in a little petroleum jelly first.

How long does it take?

The mold takes a few minutes and the silicone cures overnight, so plan on finishing the next day.

Is the finished replica body-safe?

Yes. It’s made from platinum-cure silicone, which is non-porous, washable and won’t shrink over time. Clone-A-Willy rates it Shore 20A, which means soft but durable. Use water-based lube with it.

Is it messy?

It can be. Work in a kitchen or bathroom on a non-porous surface, use the included stir sticks and a disposable cup for the silicone, and never touch uncured silicone with bare hands.
