## Emma's take

Soft where it counts, firm where you need it.

Model N is built for anyone who wants the full feeling of the real thing without compromise. The soft liquid-silicone outer layer gives under your grip and against your body, while the firm core holds its curve exactly where you need it. Reviewers consistently call out the anatomical side curve as the detail that makes the difference, angling every stroke toward deeper pressure. The wide suction base locks onto smooth surfaces and threads into most harnesses, so your hands stay free for everything else.

## Frequently asked questions

## What makes dual-density silicone feel different from a standard dildo?

The outer layer of liquid silicone compresses and gives like skin, while the firm inner core maintains the shape and curve. Most single-material dildos are either too soft to hold an angle or too rigid to feel natural. Model N sits right in between.

## Is Model N safe to share between partners?

Yes. Medical-grade silicone is non-porous, so it can be fully sterilized by boiling or running through the dishwasher on the top rack. Clean thoroughly between uses and you're good to go.

## How do I attach it to a surface or harness?

The suction cup base sticks firmly to smooth, flat surfaces like tile, glass, or a hard headboard. The base is also cut to fit standard O-ring harnesses, so it works hands-free in both setups.

## What lubricant works best with silicone dildos?

Water-based lubricant is the right call here. Silicone-based lube can bond with the silicone surface over time and degrade the outer layer. A generous amount of water-based lube keeps things smooth and protects the material.

## Is 6.1 inches of insertable length beginner-friendly?

The insertable length is squarely in the comfortable range for most people, though the 1.79-inch diameter is on the fuller side. If you're newer to penetration, take your time and use plenty of lubricant. The anatomical curve does a lot of the work once you find your angle.
