The Tube is a 6" masturbation sleeve that opens on both sides. The one I tested was red; although, it does come in clear and at least one other color. Like all masturbation sleeves, you put a bit of lube on your penis and on the opening of the sleeve, and then you slide the sleeve up and down the shaft. It is designed to give a more realistic feel than you get from simply using your hand. The Tube can be used by anyone who likes stimulation of the penis. If you are in a place where you feel comfortable jerking off, you would feel comfortable using the Tube.

The Tube is made with UR3, a fairly porous synthetic that is designed to imitate the feel of flesh. It is very soft and plushy with interior ridges that are designed to heighten the sensation when you are using it. The downside to UR3 is that is does have a synthetic odor. It's not terrible, but you will definitely notice it. The Tube is relatively thin, so you will still be able to feel the firmness of your hand gripping your penis through the Tube.

At 6" long, this will give good coverage for almost any man. As with all sleeves, it expands to handle your girth and gives a nice tight feel when it is in place. I might have preferred an opening that was just slightly larger, but it does the job once you start sliding it up and down the shaft. The Tube is lightweight and fairly discreet. It will not be obvious what it is supposed to be used for. It is small enough that it is travel-friendly.

The Tube is easy to care for; use soap and water to keep it clean. You should flip it inside out to clean the interior. Store it in a cool dry place away from light and dust and where it is not pressing up against other synthetic toys. It is fairly easy to store since it is small enough that it does not take up much space. I found it worked well with water-based lube, but you could also use a silicone lube if you prefer.

The Tube comes in a 10.5" by 5" clear plastic container. While the container is much larger than the Tube itself, it is a handy way to store the Tube, so I would keep it around. There were no instructions included, but it is fairly straightforward, so you won't miss the instructions.

The Tube does get very slippery with lube, so I would apply any lube with one hand and grip the Tube with the other. I made the mistake of having lube on my gripping hand and that made it more difficult to slide it down my penis. And then, just as I was starting to get a little annoyed, it slid down my penis and I instantly forgot about any issues with lube. It felt great and brought me to a satisfying orgasm.
