Boners «Unterstützende Penishülle» is a transparent TPE penis sleeve with internal ribs and a built-in 5 cm extension. Its overall length is 25.5 cm and its internal diameter is 3.5 cm. One sleeve is included.

The material is soft, flexible and latex-free. The toy weighs 312 g. The ribs are on the inside of the sleeve. Consider the stated length and internal diameter when choosing this product; flexibility does not guarantee a universal fit. The extension describes the toy's construction rather than a permanent change to the body.

The sleeve is suitable for use with water-based lubricants. Clean it after use with lukewarm water and a toy cleaner. It is not a condom and must not be used as a contraceptive. Keep out of reach of children and read the instructions for use.
