For years, the only glass dongs available were hugely expensive, available only to porn stars and the kinky rich - now, we are able to offer you the same high quality hand sculpted products, each slightly different from its neighbour, at an affordable price! The Knobbler does what it says on the tin - perfect for anal or vaginal use, 7 inches of stimulating bulbs create rushes of sensation when moved gently in and out. Stylishly blushed with blue at the top, this is the perfect gift for the boy or girl in your life. Each dong is made of seamless, strong pyrex for a unique sensation - either use cold from the freezer or warm gently in a bowl of hot water for different sensations. Hypoallergenic and easy to clean, this is a miniature work of art that you and your partner will treasure for years; with a little care, it will last you a lifetime.
