Unlike traditional smooth models, a knotted dildo is defined by a distinct, bulbous swelling, known as the "knot". Typically located near the base or mid-section of the shaft. This design isn't just visually striking; it is engineered to provide a progressive stretching sensation that evolves as you play.
As a flagship of werewolf-inspired fantasy toys, the Grae series features a masterfully sculpted knot designed to deliver a premium, high-intensity internal experience.
