This wand is made of Tempered glass, also known as Pyrex glass. It has the highest safety rating. Tempered glass is a borosilicate that is very sturdy and has a high thermal resistance. It also is completely body-safe and has no odor at all. This toy is made of solid glass and is not hollow, making it a little weighty. It's very smooth, with no ridges or bumps anywhere on the surface.
This 8 and a half inch glass wand has 9 bulbs starting from 3 quarter inches and getting up to about an inch and a quarter. Each bulb is slightly larger than the previous. The glass is completely clear, and the design is rather futuristic. As far as being discreet though, I can't think of a good excuse to explain what else the Icicles No.2 could be. It could travel rather easily, but would need to be wrapped up safely.
As with all glass toys, be careful when thrusting this toy, as a hard thrust in the wrong spot could cause internal bruising. The Icicles No.2 wand is great for temperature play, and it can be warmed or chilled rather easily. Before using it can be inserted in warm water or in the freezer for a few minutes. Of course, I wouldn't try switching to extreme temperatures too quickly.
The Serenity is easy to clean, using soap and water or toy cleaner. It can be used with silicone, water, or oil based lubes, and a little goes a long way. Unfortunately, this toy does not come with a case or pouch, but, being glass, it's not that difficult to store. It can also be put in the top rack of the dishwasher, according to the box.
