The toy is constructed from TPE. This material cannot be boiled to sterilize it. Cleaning should only be done using warm water and toy cleaner or mild soap. Being that it is a somewhat porous material, which you cannot sterilize, a condom should be used if you intend to share this toy with others.
The outside of the toy has very pronounced grooves, presumably to assist in manipulating the toy during use. The package indicated that there is a "ribbed pleasure tunnel." Upon initial examination of the the toy, I inserted my finger into the cavity and I did not feel anything resembling ribbing. If it is there, it is very subtle. The material is stretchy and flexible.
There was a very slight odor that I noticed when I removed it from the sealed plastic bag. Washing the toy several times did not appear to diminish the odor. The outside of the toy does not feel tacky, but hair and dust does tend to stick to it like a magnet. Thus this toy would best be stored in a zip top plastic bag after being cleaned and dried. TPE is compatible with both water and silicone based lubricants.
The visual appearance of this toy is different from others of this type. The outer sleeve is clear while the inner cavity wall is colored in one of three colors: blue, pink, or yellow. The one I received was pink. The outer ribbing on the toy made it easy to grip. The hole in the toy at the business end is about 5/8" in diameter. The length of the inner cavity is about 6" which is about as far as you would want to thrust into the toy as the diameter shrinks to about 1/16" at that point to allow air to escape during use. I found the fit of the toy to be snug but not too tight. Being of average length and girth, I would expect this toy would work for most men.
For what it is intended, this toy functions as expected. For most men, it will get the job done. It isn't too tight and has enough length to the cavity to prevent you from popping out the other end unless you really try. I am disappointed with the internal texture as I was expecting some ribbing versus the smooth texture I found when I examined the toy.
The toy is not completely silent. During use, the air escaping from the small hole at the other end of the toy tends to make a whistling sound as one pushes the toy down onto their penis.
Cleaning is fairly simple: warm water and some toy cleaner. If you don't have any toy cleaner available, mild soap will work. I found that the material was stretchy enough that I could turn part of the toy inside-out, which made cleaning and drying the cavity somewhat simpler. Since the package the toy came in is not really useful for storage, it would be best to store it in a plastic zip top bag once it has dried.
The toy came in a 9"x4.5"x2.5" box with a picture of the toy on the front and a picture of a clothed blonde woman kneeling in the background. The same picture appears on the back as well. The back of the box indicates that "the Campus Hottie can take your long rod with her 8.25" x 2.5" ribbed pleasure tunnel for an explosive finish." The side of the box includes cleaning recommendations and a reminder to use a water based lube "for maximum pleasure." The box contained the toy in a sealed plastic bag and no other items.
