We enjoyed using the Rosenquarz® penis ring during the test. The application is child’s play and can be carried out by anyone thanks to the good instructions . They are elastic, flexible, tear-resistant and stable. The ring can be worn in a variety of ways, depending on personal preference.

The design is ergonomic and the cock ring is easy to clean.
Thanks to the high-quality material, the ring is particularly flexible and stretchy and adapts perfectly to the size of the penis. The cock ring is made of 100% medical-grade silicone.
The penis ring was selected according to strict criteria and extensively tested by accredited testing laboratories. It is particularly important to emphasize that the penis ring stays firmly in place and does not slip.
