Large capacity 330ml with eight recessed water jets for a faster cleanup. The nozzle is a very flexible silicone material with offset jets to enable a free flow of fluid. Compacts nicely by storing the nozzle inside the silicone bulb when not in use. The flattened base on the bulb is upright as well. Can be safely cleaned in the dishwasher, and can be lubricated with water-based lubricants. DO NOT use silicone lubricants as they will destroy the medical-grade silicone.
