This is technically a sleeve. You insert your penis into it and stroke with it. It is a very good fit for an average penis though may be a bit short for some. It is open and can be used from either end.

The material is very soft and stretchy. It is called TPE or TPR which I believe means thermo-plastic elastomer or rubber. The business end is molded after a puckered butthole. It has a small stretchy opening which has slight raised bars in side the whole length of the tube for added sensation. It has almost no smell and no taste at all. This can be used by anyone.

It's shape is the standard tube with two open ends. The outside has a wide ridge at the front opening which graduates smaller towards the end for a looser fit at the end and the tightest fit at the front. The inside has raised bars which add to the sensation. It's fit is tight for those above 4" circumference and may tear above 5" circumference. The toy is about 5" long when stretched and may not be for those who prefer full penetration. It fits quite easily into your sock drawer.

Use a water based lube as silicon may make this degrade. Very easy to clean with warm water and dish soap. Open ended makes cleaning easier than some. Store it away from other toys as contact with other materials may mis-shape this over time.
