OLYCRAFT 6PCS Glass Petri Dishes High Borosilicate Glass Bacterial Culture Dishes with Lid 60mm Dia x 18mm Deep with 2pcs Glass Culture Plate for Laboratory School Science Project

22/24 were good2/24 were broken / defective. one dish on my order was broken. another had something black embedded in the glass.Ordered another dozen after they refunded part from my first order - all 12 were perfect, they packaged them very well and the box was properly labelled as fragile. Very happy.

These come in a variety of sizes and if you are environmentally conscious, they don't end up in the land fill as they are reusable and can be washed and sanitized to make your products at home.

Those dishes are terrible, the only positive is they are made out of glass. Seems like they have 3mm inch gap on a sides between top and bottom part, which makes them inconvenient to work with and nearly impossible to seal, in order to create clear environment inside. Do not buy it, look for something better

Why I give it one stars is because I can’t have no stars some of the rubber pieces Had holes in them I got 4 good one and when I was just putting on the rubber piece on they are garbage The Glass crumbles Up and Break into pieces Not good at all

The lid is too large making parafilm use nearly impossible. High contamination. Not useful. Cannot be stacked as they slide around very easily.
