Clone-A-Willy Kit vs Refill: Which DIY Vibrator to Choose?

Deciding between a full Clone-A-Willy moulding kit and a silicone refill? We compare the two options, explain the trade-offs, and help you pick the right one for your DIY vibrator project.
Quick answer
If you're making your first custom vibrator, go with the full Clone-A-Willy moulding kit. If you already have the mould and just want to recast or try a glow-in-the-dark version, the Clone-A-Willy Dark Blue Glow In the Dark Silicone Refill is the smarter, more affordable choice.
What you get with each option
A full Clone-A-Willy moulding kit includes everything you need for a first-time cast: the moulding tube, mixing containers, and enough silicone to create one vibrator. It's the all-in-one starter package.
The Clone-A-Willy Dark Blue Glow In the Dark Silicone Refill, on the other hand, contains two tubs of mixable liquid silicone—but no moulding tube or other accessories. It's designed for people who already own a Clone-A-Willy mould and want to make another copy, perhaps in a different color or with glow properties.
When a refill makes more sense
If your first attempt went wrong—maybe there was an air bubble or the silicone didn't set perfectly—the refill gives you a second chance without buying the whole kit again. It's also great for creating multiple copies of the same mould over time.
The glow-in-the-dark feature is a fun bonus that the standard kit silicone doesn't offer. If you already have a mould and want a custom vibrator that stands out at night, the refill is the way to go.
When the full kit is still the better bet
Newcomers to silicone moulding should start with the full kit. Without the moulding tube and instructions, a refill is incomplete. The kit also gives you the confidence that you have the right proportions and mixing tools for a successful first cast.
If you're not sure whether you'll enjoy the process, the kit is a lower-risk entry point—you get everything in one box.
Clone-A-Willy Kit vs Refill: The Trade-offs
- Full Kit: Includes moulding tube and all accessories. Best for first-time users who need everything to start.
- Silicone Refill: Silicone only—no mould. Ideal for recasting an existing mould, especially if you want a glow-in-the-dark finish. Check that you already own a Clone-A-Willy mould before buying the refill.
- Cost: The refill is priced lower (currently around $14.39) than a full kit (around $19.99). If you already have the mould, the refill saves money. If you're starting from scratch, the full kit is the only complete option.
Product facts
- Clone-A-Willy Dark Blue Glow In the Dark Silicone Refill: Contains two tubs of mixable liquid silicone for take 2, 3, 4 or 5. You can reuse your existing mould multiple times, making this refill cost-effective if you plan to cast more than one vibrator.
