Comparison
Single-density vs dual-density silicone.
Single-density silicone is one shore-hardness throughout: uniformly firm. Dual-density has a soft outer skin over a firm inner core, mimicking the feel of an erection (firm shaft, yielding surface). Dual-density costs more because the moulding process is harder; for buyers who want realism, it is the upgrade that actually matters.
| Spec | Single-density | Dual-density |
|---|---|---|
| Feel | Uniformly firm throughout | Firm core, soft outer skin |
| Realism | Abstract; honest about itself | Mimics erection / skin |
| Manufacturing | Single pour | Two pours, registered moulds |
| Cleaning | Soap + water, boil 5 min | Soap + water, boil 5 min |
| Lifespan | Decades | Decades (slightly more careful with edges) |
| Silicone lube safe | NO | NO |
| UK price range | ~£25-£70 | ~£70-£180 |
| Best-known maker | Tantus, Fun Factory | Vixen Vixskin, Tantus O2, Squarepeg Toys |
The verdict
Single-density is right for anal training, pegging, and most non-realistic abstract shapes. Dual-density is the answer if realism is the point: the soft-skin feel is genuinely closer to flesh, and the price gap closes on shorter, mid-girth pieces. For your first realistic, pay for dual-density.
