The Tenga 3D series flips the usual masturbator design inside out — what looks like an abstract sculpture from the outside becomes the internal pressure surface when inverted for use. The stretchable antibacterial elastomer accommodates almost all sizes, and the open-ended design works for solo use or as an addition to partnered hand jobs.

The Module's internal pattern is built from raised and recessed square blocks. The raised blocks rub firmly along the shaft; the recessed ones cling and create suction. The contrast between the two creates a varied, full-coverage sensation. Best with plenty of water- or oil-based lube.

Easily cleaned by inverting and rinsing with soapy water or a toy cleaner.
