To make your harness more versatile
The best option to use your sex toys with different dildos sizes.
Many harnesses incorporate a single ring size so they fit only one gauge of dildo. However, if you like to use different wingspan you can get this different diameter rings kit. This way you can perfectly fit several dildos to your harness.
They are made of silicone so its cleaning is very simple with water and neutral soap. In addition, they do not produce allergies.
