Bests & Worsts Reviews from Amazon

I am a college professor and have used slides similar to these many times in anatomy and physiology lab. I got these for my son's 4th grade classroom and am pleased. The quality is just as good as the ones the university purchases. The slide box is wooden and the slides fit inside perfectly. None were broken during shipment. The quality of microscope used will make a big difference in what one can observe from the slides. One with a100x objective and immersion oil is preferred but a 40x objective will also work, just with a less magnified and detailed image.
