50 Pieces Microscope Slides and 100pcs Pre-Cleaned 20mm x 20mm Microscope Cover Slips Glasses for Basic Biological Science Education

These are more thin and fragile than I expected but they work fine and there are plenty.I'm not to experienced so maybe it's normal now but I remember som real thick glass from grade school

Great project extras. For new learners

I love these, they are perfect for whatever you are doing. I bough them to just look at general stuff under a microscope (40,100,450,1000 total zoom), and they work fine.they are very clear and very easy to clean. I have not broken one yet, but still, they are very durable. Even when I looked at my own blood at 1000 zoom, I could barely tell that the slides were there, and I got crystal clear images. I would rate these very well, and a 100% buy for anybody wanting to learn something about the microscopic world. I had a lot of fun with them, and I havn't even gotten around to using all of them. If you buy these, I recommend buying an additional dye, my top 2 being iodine or methyl blue. For the price, I would buy these again.

Product is as advertised, delivery prompt. Would use this vender again

Exactly what I needed. Good quality.

I have a microscope that I mess around with to look at microorganisms in the nearby ponds. I am not an expert or a scientist or anything, but these work well for me. They seem a little cheap, but I am not sure what else a piece of glass is supposed to feel like. They are easy to clean and reuse as well.

About 50% of the slides are chipped or otherwise damaged. Very dirty as well, needed to be cleaned before use. Cover slides were also dirty and package was missing the pipettes.

Awesome exactly what i needed
