## Emma's take

Dual-function hollow design for confidence and shared pleasure.

This dual-purpose hollow extension works whether you're starting with something or nothing at all. The crystal jelly material feels lifelike and flexible, while the vibrating tip adds sensation for both partners. I love how versatile this is — it gives confidence to anyone wanting extra length or girth, and the hollow design means it works with any body. The lavender color is unexpectedly pretty, and the jelly material warms to body temperature quickly.

## Frequently asked questions

## Does this work for both penis extension and strap-on use?

Yes, the hollow design works either way. You can use it as an extension if you have an erection, or as a strap-on if you don't. The flexible jelly material accommodates different sizes comfortably.

## How strong is the vibration in the tip?

The vibration is gentle to moderate — designed more for added sensation than intense stimulation. It uses AA batteries and provides a pleasant buzz that both partners can feel during use.

## What's the best way to clean this jelly material?

Use antibacterial toy cleaner and warm water, then air dry completely. Since jelly is porous, thorough cleaning after each use is important. Store in a breathable pouch rather than sealed plastic.

## Is this compatible with condoms?

Yes, you can use condoms over this extension for easier cleanup and safer sharing. Choose a larger size to accommodate the added girth comfortably.

## How do I know if this will fit comfortably?

The jelly material has good stretch, so it accommodates a range of sizes. Start with plenty of lube and go slowly the first time to find your comfortable fit.
