Glass dildos are usually very prized and a very unique dildo experience. They are completely smooth and very little lube is needed to make the very slippery because they have a non porous surface. Most glass dildos are very fun to look at on your shelf or to take to bed or the bath with you. They are usually safe in the dish washer and made to last. Glass dildos are usually pretty heavy which adds to the sensation of something and adding to the substance of the device.
