Hollow Stainless Urethral Sound
The Ritual
As evening settles and the world quiets, a private ritual begins. The Hollow Stainless Urethral Sound rests cool in your palm—a seamless extension of intention. Its weight is reassuring, its mirror finish catching the low light as you settle into stillness.
Design & Material
Forged from solid stainless steel, the piece is polished to a glass-smooth finish, then hollowed to create an open channel. This thoughtful negative space allows for a continuous, subtle flow of sensation, making each movement feel intentional and unhurried. The metal warms to the body, responding to your temperature and touch.
Sensation & Rhythm
There is no rush here. The smooth, rounded tip glides with ease, following natural contours and inviting a slow crescendo of feeling. Because it is hollow, the instrument offers both presence and passage—weight without obstruction, intensity without force. It is an invitation to listen inward, to rediscover rhythm and breath.
Care & Keeping
Rinse with warm water and a mild, unscented cleanser after each use. Pat dry and store in a soft pouch, away from other metals. With simple care, this piece remains a lasting companion for your private wellness practice.
- Wash with warm water and mild soap before first use.
- Apply water-based lubricant as needed.
- Clean thoroughly with toy cleaner after each use.
- Store in a cool, dry place, ideally in a pouch.

Bought this for my husband because he’d been curious about trying something with an open channel. His first impression was that it looked a bit intimidating, but after the first careful try he said the weight and balance made it feel much less fiddly than he expected. The hollow center was the detail he kept mentioning, and now it’s part of our occasional wind-down routine. Shipping was quick, box was plain, nothing about the outside gave away what was inside.

For thirteen bucks, I didn’t expect a lot, and mostly this delivers on the basics. The steel is smooth and the hollow channel is a nice touch compared to my old solid one. That said, my order showed up two days later than promised, and the open tip means I’m spending extra time cleaning the channel after each use. It works, but I keep reaching for my old one when I don’t want the fuss.

After a few weeks with this, the finish really does feel flawless. It has a nice weight in hand, and the hollow channel adds a subtle shift in sensation I wasn’t expecting. I’ve used solid sounds before, and this one is easier to keep steady once everything is settled.

Five weeks in, I still can’t find a single rough edge, and the hollow channel makes a bigger difference than I expected.

Honestly, I was skeptical that a hollow sound would feel all that different, but it does. The steel is polished and balanced. My only gripe is that the fit took patience to get used to; I had to go slower than expected and use more lubricant than usual. Once I adjusted, though, it was worth the effort.
