Query: Not really for a microscope

If you are looking for prepared slides to view under moderate magnification with a microscope, these slides are not for you. They are made by scotch-taping large specimens onto a glass slide. Since they are not thin enough to transmit light, they are more suitable for a dissecting microscope with top illumination. The Konus brand is much better quality.
