Strap-on harness with dildo This strap-on harness is handmade and has decorative studs on the front. Thanks to the buckles, the circumference is adjustable. The strap-on comes with a removable and interchangeable silicone dildo (Ø 3.5 x 12 cm) which is attached with a screw cap. We sell 6 different dildos with the same screw cap system, which can be easily attached to this strap-on.
