## Emma's take

Soft where it counts, firm where it matters.

Six inches of hyper-realistic dual-density silicone, with a soft outer layer that gives like skin and a firm core that holds its angle through anything. The suction cup is strong enough to free both hands, and the flared base slips straight into a harness. Reviewers reach for Model A when they want the full weight and feel of the real thing without compromise. Bodies that prefer generous girth and confident depth will feel exactly that, right from the first use.

## Frequently asked questions

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

Model A has two distinct layers: a soft, skin-like outer silicone that compresses and gives under pressure, wrapped around a firmer core that keeps the shape and angle steady. The result is a combination that reads much closer to body tissue than a single-density toy can manage.

## Is Model A safe to use with a strap-on harness?

Yes. The flared base doubles as a harness-compatible plate. It fits most standard o-ring harnesses, so you can move between suction cup and harness play without any additional accessories.

## What kind of lubricant should I use with this dildo?

Water-based lubricant only. Silicone-based formulas can interact with the silicone surface over time and degrade the soft outer layer. A generous application of a good water-based lube keeps things comfortable and protects the material.

## Can Model A be fully sterilized and shared between partners?

Yes. Because it is 100% silicone with no porous materials, you can boil it for three minutes or clean it with a diluted bleach solution between partners. Standard soap and warm water is enough for single-partner use.

## How strong is the suction cup, and what surfaces does it stick to best?

The suction cup is designed to hold firmly on smooth, non-porous surfaces: glass, tile, and sealed hardwood are reliable. Textured or porous surfaces like some bathroom tiles or painted wood will hold less securely. Press the base flat and twist slightly to set the seal before use.
