One-Thumb Spray is a water spray gun for home use like car washing and garden watering. By combining the on-off button and flow adjustment mechanism, the spray becomes easier to control and clean. The water flow can be controlled with only one thumb. Together with a simplified and ergonomic grip design, users can have a brand new watering and washing experience.
