This handy little penlight is a staple for medical pros, students, or even for home use. It's made from medical-grade aluminum alloy, so it's durable, easy to clean, and safe for patient exams. The bright white LED is perfect for checking ears, nose, throat, or pupils. On the side, there's a pupil gauge and a 5 cm ruler – super useful for quick assessments. It turns on and off with a simple click button. It's lightweight and has a clip so you can attach it to your scrubs, pocket, or lanyard. Runs on 2 AAA batteries (not included), and you can just replace them when they die. Comes in a 2-pack (green body). Great for nurses, doctors, EMTs, vets, or for your home first-aid kit. Also works as a general-purpose mini flashlight for camping or DIY tasks. A reliable, affordable tool that does its job well.
