A dildo that is an exact replica of your own penis – or your partner's? That's exactly what Cloneboy makes possible. With this clever molding kit, you can make an impression at home and cast a realistic silicone dildo from it. In this detailed step-by-step guide, we'll show you how the molding works, the importance of timing, the available variations (vibration, glow, candle), and how to avoid common mistakes. 🍆✨

🎁 What is Cloneboy?
Cloneboy is a DIY impression kit that allows you to create a faithful replica of an erect penis. The principle: First, a negative impression is made using a fast-setting molding compound (alginate). Then, liquid silicone is poured into this mold – after curing, you'll have your very own personal dildo in your hand. A unique gift and a guaranteed one-of-a-kind item.
📦 What's included in the set?
Every Penis Cloner Kit contains everything you need for a complete cast:
- Molding powder (alginate) for the impression
- Silicone components (base + hardener) for the dildo
- Molding tube / container
- Stirring stick and instructions
You choose the color in advance: There's the kit in skin tone and the kit in pink. All sets can be found together in our Cloneboy collection.
🧰 Preparation – how to get started stress-free
- Room temperature: Work in a warm room (approx. 20–25 °C). Water that is too cold or too warm will drastically alter the setting time.
- Have everything ready: Keep the kit contents, lukewarm water, a towel, and a watch/stopwatch within reach – every second counts from the moment you start mixing.
- Ensure arousal: The penis must remain fully erect throughout the entire impression process. Plan for this and take your time warming up.
- Trim pubic hair: This will make demolding much easier later and prevent pain when pulling out.
⏱️ Step-by-step: How to clone your penis
- Mix the molding compound: Mix the alginate powder with lukewarm water according to the instructions, quickly and without lumps. Important: The alginate sets quickly – you only have about 60–90 seconds.
- Take the impression: Fill the tube with the mixture and immerse the erect penis centrally. Hold still and do not move until the mixture is firm (approx. 2–3 minutes).
- Carefully pull out: Once the alginate is firm and rubbery, slowly and straightly pull out the penis. Now you have a perfect negative mold.
- Mix the silicone: Thoroughly mix the two silicone components in the correct ratio until the color is uniform.
- Pour in: Slowly pour the liquid silicone into the alginate mold. Gently tapping the tube will release air bubbles – this ensures a smooth result.
- Allow to cure: Now it's a matter of patience: The silicone needs several hours (overnight, depending on the set) to fully cure.
- Demold: Carefully break open or peel away the alginate mold – and your finished dildo will appear. 🎉
🌡️ Timing & Temperature – the most common mistakes
The alpha and omega with Cloneboy is timing. These points determine success or failure:
- Mixed too slowly: If the alginate thickens before the penis is in, the impression will be messy. Only mix when everything is truly ready.
- Water temperature: Warmer water speeds up curing, colder water slows it down. Stick to the instructions.
- Lost erection: The most common reason for failed attempts. Tip: Only start mixing just before immersion.
- Air bubbles in the silicone: Pour slowly and gently tap the tube.
No need to worry if the first attempt isn't perfect – with a silicone refill pack, you can simply try again.
📳 The Vibration Variant

Do you want to make a vibrating dildo instead of a rigid one from the impression? Then the Penis Cloner Kit with Vibration (Pink) or the Kit with Vibration in Black is exactly what you need. The vibration insert is placed in the center of the silicone mass during pouring – after curing, you'll have a dildo that vibrates at the touch of a button. More inspiration can be found in our guide to vibrators for self-pleasure.
🌙 Further Variations for Creatives
- Glow in the Dark: The Glow-in-the-Dark-Kit uses luminous silicone – your clone glows in the dark.
- As a Candle: The Candle-shaped Penis Cloner doesn't form a dildo, but a decorative candle – a fun, very personal gift.

🍑 Usage: Suction cup & Strap-on
You can enjoy your finished clone in many ways. The Cloneboy Dildo with Suction Cup adheres to smooth surfaces like tiles or shower walls – for hands-free fun. And with the matching Strap-on Harness Set, your casting becomes partner-friendly. Our Strap-on Guide explains how to properly put on and use a strap-on.
🔁 Refill & try again
The set is reusable – you just need new silicone. Choose between the practical silicone powder for refilling or the ready-made refill packs in pink and black.

🧼 Cleaning & Care
Clean your finished dildo before and after each use with warm water and a mild toy cleaner, and store it dry. Use only water-based lubricant – silicone-based gel will damage the dildo's silicone. More on this in the lubricant guide.

What if the first attempt fails?
No problem – with a silicone refill pack, you can simply start again. The most common mistakes are incorrect timing and a waning erection.
