Dr Clockwork Rolling Drum. This spiked rolling drum, much beloved by our own Miss Patience Virtue, is a sensation toy. On its own, it gives a feeling not unlike a massage. However, when used on skin that is Tender, the sensation becomes at once more intense! Should you add the Violet Wand, it gives a desirably punishing sensation. It measures 2.8 inches long; the drum itself is 0.9 inch wide, with a 0.5 inch diameter. The handle features a grooved grip, and the drum is formed of no fewer than eighty four triangle like raised bumps. What a joy!
