Here is our extra-long style urethral stretching insert. It is made from the same high-quality, durable silicone material as all our enema nozzles. With its polished rounded tip, this probe goes in smoothly, giving just the right level of comfort all along the urethral pathway into the bladder with a total insertable length of 12'' and 18'' up to the flanged style base. This probe can be purchased with an open core for extended-length wear to accommodate drainage or with a completely solid configuration. It has a 7mm diameter, .275'' outside diameter, or 21.2 french size.
The silicone material is very flexible in this small diameter. If you want something fairly rigid, you must select the highest number in the firmness selection box. It is available in varying levels of firmness, but in this small size, there isn't much difference except for the very firm selection. The open-core option allows the piece to act as a catheter.
