An eye dropper is a small device used to administer liquid medication directly into the eye. It typically consists of a squeezable bulb attached to a narrow, pointed tube. When the bulb is squeezed and released, it draws liquid into the tube, allowing for precise drops to be dispensed.
The image you provided shows four different sizes of eye droppers: 3ml, 5ml, 10ml, and 15ml. Each size is available in packs of 144. The droppers have a translucent body with measurement markings and come with a non-sterile screw cap.
