Review on 2-Pack CAVN LED Penlights With Pupil Gauge For Nurses & Doctors - Reusable Medical Penlight Set For Nursing Students (Black & White) by Michael Vargas

Super bright! Know that it does not come with batteries, so you will need 2 AAA batteries for each pen. I needed these for nursing school and they are perfect.Edit: Only thing I dislike about it is that because the button is so easy to push, I always find it accidentally turned on. I wish there was some kind of lock to keep it from accidentally being clicked all the time. Other than that, still good.
