The text of the paper insert of this Buttman butt plug claims "viewable curves" and they are definitely not lying. It really does enhance the vision of the anal canal; if anything, my complaint is that it could be bigger to more fully fill out the butt for an even better view. The interesting bit on this butt plug is the miniature handle. At first I was mystified. I thought that it might be a crank to spin the plug. To the best of my investigation, I believe the handle is meant as a vision assist for the person looking in. The thing about the base of this plug is that it is really likely to fall out of your butt due to the bottom-heavy weight of the plug; this makes it pretty unfit for "wearing," so don't expect any long-term insertions with this piece. That being said, the curves are a very nice texture and they make for some pretty great sensations.

The Buttman curves plug is made of glass, so that means it can be used with any type of lubricant or condom that your body is compatible with. To clean it, you can wash it with soap and warm water, but like any anal toy, make sure you are very thorough cleaning it. This is a body-safe, non-toxic toy.

Overall I thought this was a fun and interesting addition to my toy collection. I really enjoyed seeing deep within, but generally I wish it had more girth and weight at the top. This could be a great toy for beginners, since the girth is not threatening and there's no chance of it getting "stuck up there." If you are a curious anal pervert (a term I use affectionately), this could be the toy to get your partner(s) interested in "opening up" for your viewing pleasure.
