500pcs Hemocytometer Glass Cover Slip, 26mm Length, 22mm Width LAB Professional Glass Cover Slips

Excelent

These cover slips shipped in thin cardboard boxes, inside a sealed plastic bag. Some of the boxes showed dents. However, there was zero damage, with all cover slips in good shape.They are glass, very thin, and work well with my grandson’s microscope.Despite the apparent fragility, I have dropped two of these, from standing position onto the floor, and they did not break or crack.Having 500 in the order, I feel it’s a great deal for the price.Recommended!

The slips are fine. But they came in these cheap, flimsy boxes that no one would ever store, use or ship them in! Made in China…. I should have expected that kind of low quality container. I ordered some several years ago from a U.S. manufacturer and they came in a hard plastic container and insulated with foam… serious, can’t the manufacturer make at least a little effort?

Each set of slides are wrapped in a small sheet of tissue paper. I've opened one box and all #500 were intact, clean.

All the cover slips of the five boxes were covered with mold at their arrival, despite the fact that the boxes came inside a sealed plastic bag.

The thickness is not 0.5mm. It is much less. It is only about 0.32mm thick.
