ERGO is a smooth silicone plug with a flared base and ergonomic kidney-shaped design. OXBALLS high-quality Liquid Platinum Silicone is rubbery and flesh-like, perfect for comfortable insertion. The soft silicone flanges at the base keep ERGO securely snug between your cheeks.

Each unique ERGO BUTTPLUG is hand poured right here in the OXBALLS factory so no two plugs are alike.
