Sono No.36 Stretchable Transparent Thick Extension Maximum

Push beyond the modest girth boost of smaller sleeves. This transparent extension adds 25mm of length while delivering 10mm extra diameter around the shaft, creating a genuinely noticeable size increase your partner will feel. The thick TPE material holds its form under pressure while stretching comfortably to your dimensions.

A ball strap anchors the extension in place through active motion, preventing unwanted shifting so you stay positioned exactly as intended. The transparent design lets your natural shape show through the added bulk. Reach for this sleeve when you want the size increase to be unmistakable and central to the scene.
