Silo is a beautifully crafted silicone butt plug that was designed for prostate stimulation while massaging the perineum. The unique shape is easy to insert and the luxurious brushed silicone material provides a secure yet comfortable fit. It works well for first-timers or those who prefer a plumper contour. Silo is waterproof and made of smooth, flexible silicone making it easy to insert & wear comfortably. Its silicone skin means it’s easy to clean and keep clean! We recommend a water-based lubricant with this item.
