The FLIP HOLE includes two sample pouches of TENGA HOLE LOTION [REAL].
We recommend using TENGA HOLE LOTION for further uses. Please note that while the material of the interior (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.
