This plug is made out of glossy black glass. It feels cold in the hand (unless you warm it up) and is completely smooth all the way around. It has no odor when it arrives and will not hold onto odors either. It is completely non-porous and will require even less lube and cleaning than a silicone toy. Since it's made out glass it is extremely rigid and has absolutely no give to it. This is not a toy for someone just starting out exploring anal play.
This plug's design is almost identical to the Sexy spades medium (also by Doc Johnson) which also comes in a smaller size as well. While difficult to get in, this design helps aid retention and is very comfortable once inserted. The base easily sits between the butt cheeks making sitting down or walking around with the plug in a possibility. This plug has a fairly long neck which is a large part of the reason why it is so comfortable. The head has a smooth transition from small diameter to large and the only issue is the large overall diameter. While its base is actually the same size as the head, there should be no worry of this plug accidentally being sucked in as the transition in size from the neck to the base is very quick.
Adequate warm-up is a must for this plug and you should be comfortable with anal toys at least 1.75" in diameter or larger and have the time to devote to getting this plug in. Once in, this plug is surprisingly comfortable for its size. It could easily be worn for long term wear. It does not provide enough stimulation on its for orgasm so other stimulation combined with this plug is your best bet if you're seeking orgasm. There really aren't any bad things about this toy only a caution on the toys size.
Because this plug is made out of glass, care should be taken not to drop it or throw it around. It comes with a nice foam insert and this would be a good place to store it when not in use. If you see a chip or crack on this toy you should not continue using it as this could cause serious injury. This is not a huge concern though, and shouldn't scare you off if you've never tried a glass toy since almost all are made out of Pyrex glass which is very strong and less likely to crack or chip than regular glass. If you've never used a toy made out of a hard material like glass or steel you should get a toy at least a quarter inch smaller in diameter than the largest size silicone or rubber toy you feel comfortable with.
There are no limitations on what kind of lubricant this toy can be used with and it can be sterilized either by boiling it in water or soaking it in bleach. Sterilizing is a must if you are sharing this with a partner. If you're not sharing this toy then a simple rinse with soap and water is more than adequate and with minimal care this toy should last for a long time.
This plug comes packed in a thick cardboard package with a foam insert inside holding the toy in place. The packaging is definitely not discreet but the foam insert (fairly discreet) inside can be taken out and used on its own for storage. The packaging has very little information although it does serve fairly well for storage either with or without the external cardboard box.
This plug looks deceptively small when you're just looking at it. It's not until you're trying to insert that you realize how big it really is.
