Rouge's Stainless Steel Rosebud Urethral Sound 12-piece set is ideal for beginners. Because you can work your way up from the smallest to the biggest pleasure!
If you're interested in probing (or urethral penetration, if you prefer), you know that this practice is not something anyone should embark on without prior research, time, patience, and a great set of high-quality tools. These are the tools!
Dimensions:
Each probe (except the first, which is straight and 29.21 cm long) is identically shaped and about 30.5 cm long. The size and thickness of each tip ranges from 0.1mm to 120mm, so you or your partner will be able to choose the one that best suits your experience level and/or stimulation requirements.
