Dive into a brand - new sounding adventure with the Master Series Invasion Silicone Urethral Sound Trainer Set. These body - safe rods are made from top - notch silicone, which not only makes them easy to sterilize but also ensures a worry - free experience. Their flexibility allows them to bend along with your body, smoothly sliding down your shaft to bring you that one - of - a - kind sensation you've been longing for. Each rod is double - sided, featuring different girths on each end. With graduated sizes, you can gradually work your way up until your urethral opening can comfortably fit the largest rod. What's more, this set is phthalate - free and made of non - porous silicone, offering a hygienic and safe option for your exploration.

Using this set is quite simple. First, make sure your hands and the rods are clean. You can use a mild soap and warm water to clean the rods, or follow the sterilization method recommended for silicone products. Then, apply a water - based lubricant to the rod. Gently insert the smaller end of the rod into your urethral opening and slowly slide it in. As you get used to the size, you can start using the larger ends or move up to the next rod in the set. Remember, take it slow and don't force it. If you feel any pain or discomfort, stop immediately. After each use, clean the rods thoroughly and let them dry completely. Store them in a cool, dry place, away from direct sunlight and sharp objects. This will help keep the rods in good condition and ensure a long - lasting product.
