The Rosebud Urethral Sounds are about 12 inches long. The rosebuds start at 4mm and go up to 15mm in size. They are VERY stimulating with their rosebud tips. Made from 316LVM Surgical Steel so there is nothing but the best in materials.
You should never force anything, as soon as you feel pain or resistance; it's time to move to a smaller sound. It is very important when using sounds to please use common sense and make sure that you have researched urethral play fully before you start.
