The essentials
Fun Factory IKU TIGHT: what you need to know before you buy
Is it for you?
Who the Fun Factory IKU TIGHT is for, and who it isn't for
It suits you if…
- You want a masturbator with a tight fit.
- You want a small, light piece, 7.4 cm on each side and 86 g.
- You like the idea of a modular system you can expand with other IKU models.
- You prefer a silicone sleeve that comes out and can be washed with soap and water.
Better look elsewhere if…
- You prefer a textured interior. In the same range, the IKU FLEX is the one with an interior structure.
- You want the most compact version in the range. That is the IKU TIGHTER, which weighs 100 g.
- You use silicone lubricant. With a silicone sleeve, a water-based one is best.

Step by step
How to use the Fun Factory IKU TIGHT
- Wash it before first use with warm water and mild soap, and dry it well.
- Apply water-based lubricant to the sleeve and to yourself. The fit is tight, and it glides better with lubricant.
- Start slowly and set the pace and pressure yourself with your hand.
- Combine it if you have other IKU models. All models share the same frame and have the Magnetic-Click system.
- Wash it afterwards and let it dry completely before storing it.
Cleaning
The sleeve is removable: take it out and wash it with warm water and a little mild soap, or with a toy cleaner. Rinse well and let it dry completely, inside as well, before storing it.
Our tips
- Do not use silicone lubricant: it can damage the surface of the sleeve.
- Stop if you feel pain or discomfort.
- If you share it, wash it before someone else uses it.
- Store it dry and clean.
