What should I use for lubrication with the FLEX?

The FLEX includes a sample pouch of TENGA HOLE LOTION.

We recommend using TENGA HOLE LOTION for further uses. Please note that while the material of the sleeve (TPE) should be compatible with other water-based lubricants, we cannot be held responsible for any damage that may occur from third-party lubricants.

Oils and silicone-based lubricants should not be used, as these can damage the material.
