QWORK Sterile Glass Petri Dish Petri Plates with Lid,5 Pack, Thicken, 90mm x 20mm

Bought these for the price. Giving 5 stars because they appear to be good quality glass - they autoclave fine. However as other people have noted there is a sizable gap making them ill suited for agar plates or do plan on using a lot parafilm to ensure they're sealed. I found it a pain and I found a pack of "20Pack Round Clear Frosted Plastic Bead Storage Containers Box Case with Screw Top Lids,Cylinder Stackable Bead Containers for Make Up,Eye,Pills,Gems,Beads,Jewelry,Small Items,2.6x1 Inches" on Amazon for twice the price but much better for mycology and they're autoclavable - although twice the price you get 4 times as many making them a better value.

No breakage all shipped successful

horrible fitting lids, 4 of 5 were broken as well

These petri dishes were actually a great deal, slightly thicker than your average plastic petri dish, but not as premium feeling as PYREX branded dishes. To contrast that you don't pay anywhere near what a single Pyrex dish would cost for this set, so I am very pleased with my purchase!I bought with the intention of painting the underside to study the way different liquids react to vibration/sound/frequency. Then recorded the visuals on 120 black and white film- a mixture of science and fine art :). Would gladly purchase again if needed! Highly recommended them!

I dropped to 4 stars because while everything seemed perfectly packaged, bubble wrapped, and protected with air bags. Still one arrived broken. I guess they aren't as durable or maybe the shipping company not careful. Worth nothing no warning of fragile on the package.

I recommend it. Nicely packed and good quality

Expect to receive broken dishes. Order extra.

They haven't broke even after being short dropped. Very impressed!
