## Emma's take

Eight vibration modes wrapped in their signature FlexSkin silicone.

I've tested a lot of couples' toys that promise "real feel," but Shaft's FlexSkin actually delivers on the hype. This vibrating sheath adds length and eight distinct vibration patterns that both partners feel clearly. The wireless remote means you're not fumbling with buttons mid-session, and the boost function gives you that extra intensity right when you need it. Size 1 fits most comfortably without feeling too snug. Fair warning: the lifelike texture is so convincing it might spoil you for anything else.

## Frequently asked questions

## How does the FlexSkin material feel compared to regular silicone?

FlexSkin has a much more lifelike texture and temperature responsiveness than standard silicone. It warms to body temperature quickly and has a realistic give that mimics skin rather than feeling like a typical toy material.

## Can both partners feel the vibrations during use?

Yes, the eight vibration patterns are designed to transmit through both the sheath and to the receiving partner. The boost function adds extra intensity that's felt mutually during peak moments.

## What's the range on the wireless remote?

The remote works reliably up to about 25 feet, so you can hand control to your partner without staying right next to each other. Perfect for tease-and-please scenarios.

## How do I clean the FlexSkin material properly?

Wash with warm water and a toy-safe cleaner, then let it air dry completely. Avoid silicone-based lubes as they can break down the FlexSkin over time. Store in the included case once fully dry.

## Is Size 1 adjustable or should I measure first?

Size 1 has some stretch but works best for average girth. The internal diameter is 0.9 inches, so measure if you're unsure. The FlexSkin does have give, but a proper fit makes all the difference in comfort.
