Boreal Student Monocular Compound Microscope 4x 10x 20x H10X At the time of this listing, I have a quantity of these and so you may not receive the exact one shown in the pictures, but they are all in the same or better condition. All of the mechanisms work fine, and I can see clearly through the eyepiece and objectives. This takes two AA batteries (not included) for the illumination light. Q7-8 fdk 80616228 81126248
