FUN FACTORY B Ball Uno The FUN FACTORY B Ball Uno is a sleek, compact plug designed to create a more natural kind of internal pulse. Instead of vibration, its weighted inner ball responds to your movement, sending subtle waves of sensation through the body with every shift, step and slow surrender. With its tapered tip, smooth body-friendly silicone and compact 2.87-inch length, B Ball Uno offers a confident introduction to deeper play while still feeling refined, secure and beautifully easy to use. The flat base keeps it comfortably in place, while the rounded shape delivers a fuller feeling without overwhelming the body. Waterproof to IPX7, battery-free and simple to clean, B Ball Uno is made for shower play, bath play, solo exploration or partnered teasing. Add a generous amount of water-based lubricant and let the internal weight create a quiet rhythm that builds naturally with your movement.
