The No. 37 is made of black glass. It has a very classy look to it. Since it is made of glass it retains temperature quite well, so it is a great toy for sensation play. Glass is firm and should therefore be used very cautiously.
Glass is non-porous, has no taste or smell, and cleans quite well. Glass is smooth and is very slick with lube. It does not feel realistic; it very obviously feels like glass.
The slick quality of the glass makes it really easy to insert and begin a sexual exchange.
The tip of the shaft is shaped like a pointed tulip. The tip does not feel pointy during use. The tip is tapered, so it makes anal insertion very easy and comfortable.
The shaft is covered with three rows of nubs that are prominent enough to be felt in use, but not too much as to become bothersome or irritating.
The base of the toy is quite large and round. The end of the shaft resembles a pacifier with its loop handle. The loop handle is quite big, enough for one female finger to go through quite easily. If your fingers are full of lube, it will be hard to get a good grip on the handle.
The one and a half inch width can be considered as an intermediate anal player size. You may need some warm up with another toy if you use this one anally.
This toy does not look realistic and is not very discreet in appearance; it's a bit more discreet than a realistic skin toned dildo.
The glass is so smooth, it makes anal play a delight. Using silicone lube with the glass is so much more enjoyable than water based lube, since silicone lube will last longer.
For vaginal play this is not very ideal, as it has no curve and is a bit short. It is unlikely to reach the g-spot (it hasn't reached mine). However, for anal play it is awesome; it can be fully inserted with practice, and the handle is awesome to grip on for slow thrusting. I think glass is my all time favorite anal toy material.
The nubs are really intense, so you must thrust with care. Do not thrust quickly, or you may have a sore or tender asshole afterwards.
Glass is easy to care for. It is compatible with all lubes, and it is non-porous so it doesn't harbor any bacteria. It cleans easily with soap and water, but you must be careful to dry it with a soft material so as to not create scratches on the glass.
I store it in an EdenFantasys toy pouch.
