ULAB Glass Petri Dishes, Tissue Culture Plate, Dia.100x20mm, 3.3 Borosilicate Glass Material, Pack of 5, UMS1003

Purchased these as dwarf shrimp feeding dishes for my aquariums. They arrived well packaged and all were unbroken. The top and bottom are equally sturdy so I effectually have double the feeding dishes. I cannot comment on use of this item for other purposes, but for my needs the dishes are great. Price was very reasonable.

I bought these to use as feeding dishes for my shrimp. I got 10 dishes from 5 Petri dishes with lids for less than the price of 2 Feeding dishes. Can't beat that, and they work just as good too.

Using petri dishes to feed shrimp. They are much cheaper than "shrimp" glass dishes but they are exactly the same. Thank you!!!

These are pretty cheap and easy to break. They were packaged terribly for what they are. We had to return the first box because one arrived broken. We were sent a replacement and that one was fine.

three out of five petris made it two were broken.Ill take it no big deal.

As expected, packaged well and arrived in one piece.

The top is a little bit TOO big. Needed to be just a little bit smaller to fit perfect for me. You can't really use the tape needed to seal off the edges. On the positive side, putting it in a pressure cooker didn't crack or break it.

The top is too large, leaving a large gap that begs to allow contamination
