It's made of perfectly smooth, odorless pyrex glass. Because it's pyrex, it's more resistant and durable than plain glass. The coil that runs down the shaft provides intense stimulation when it's being inserted, and moving it slowly provides intense stimulation. People who don't appreciate lots of ridges will probably not like this texture.
I like the design, as it's comfortable to hold. My lover prefers me to hold straight dildos at a sharp angle, which is tough on my wrist, but it's the best way to stimulate her G-spot. This curved dildo hits the spot without a lot of pressure on my own wrist. It's not super thick, but still substantial enough to please most users.
The ridges significantly intensify the sensation of insertion, while the curve and the bulbous ends are designed to heighten the initial insertion and hit and stimulate the G-spot. The ridges themselves also can stimulate the G-spot area when it's deeply inserted. Glass is strong and unyielding, perfect for those who like a super firm product, and a very slight rocking motion with this dildo can cause intense sensations. Be careful not to thrust too hard or deeply with glass, as it can be painful. Start with slow and steady thrusts and build up at the receiver's pace.
This toy can be sterilized with a 10% bleach solution or with a hot wash in the top rack of the dishwasher, or boiled. Handle with care when hot, let it cool before trying to move it. Otherwise, it's easy to wash with soap and water for those times when you don't need it sterilized for sharing.
The padded purple micro-suede carrying case is almost the best feature of this glass dildo. You should definitely keep it for everyday storage and especially for travel.
