They bulb syringes have tapered tip, that allows for precise suctioning and irrigation of wax or liquid from ears or wounds. The bulb can be used to blow air in a controlled manner, making it suitable for cleaning various items, such as cameras, computers, motherboards, precision instruments, and more. To use the syringe, squeeze the round portion to collapse the syringe, bring the syringe to the desired area and release your grip. The 1 oz ball on each bulb provides the perfect amount of compression for both suctioning and blowing.
