United Scientific™ CSTK02 Concavity Glass Slide, 3mm Thick, 2 Concavities, 75mm Length, 25mm Width, Pack of 12

Good quality and individually wrapped. Beware of the 3mm thickness, "about twice the thickness of regular", won't fit standard storage box.

Great quality and clarity. The double well is extremely handy for the microscopy work. Even has beveled edges.

These are really thick! Several of them were not entirely clean, right out of the package.

Purchased this with the microscope and a hemocytometer early in the lockdown homeschooling days. It allowed me to do backyard science experiments with the seven year old. Was perfect for the "Hay Infusion" experiment. Highly recommend.

AWFUL. They're thick, which can be desirable, but they look like they were ground by an eight year old using a belt sander. I mean, could you at least grind them smooth so there aren't grooves obscuring the subject?

Nice thick slides with a decent depth and smoothly polished cavity.

Wow! These are quality slides. They are thick glass individually wrapped in plastic. These will make our impromptu science observations so much easier than having to wait for nail polish to dry. Thank you!

Good value.
