Is it for you?

It suits you if…

- You want a strap-on harness that fits at the waist and thighs.
- You need a strap-on that either partner can wear.

Better look elsewhere if…
- You want a solid dildo, because this one is hollow inside.
- You want something slim: 5 cm wide is more than a ping-pong ball (4 cm).
- The hollow's measurements (12.5 cm long and 3.5 cm in diameter) are too small for you.

Our usage tips
How to use the Fetish Fantasy Extreme Hollow
- Slide the straps until the waist is snug and the thigh straps are tight.
- Connect the plastic clips at the back by snapping them together. This keeps the strap-on from moving.
- Use plenty of lubricant before you start.
Cleaning
After each use, clean it with toy cleaner and warm water. Our tip: wash the inside of the hollow too, rinse well and let it dry completely, inside and out, before you put it away. Don't boil it or use disinfectants.
Our tips
- With silicone, use water-based lubricant: silicone-based ones can damage the surface of the toy.
- If you wear it with a penis inside, put a little water-based lubricant in the hollow too.
- If you use a latex condom over the dildo, no oils or oil-based lubricants.
- At 5 cm wide, go slowly and stop if there is pain.
- If it moves from the anus to the vagina, wash it first or change the condom.
- Keep the straps firm but not cutting in: if you notice tingling, coldness or marks on the skin, loosen them.
