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

Great small storage containers for a cheap price. Hold loose beads, or nicnacks great. These are actually awesome. Got them for being able to sanitize stuff and they hold up in the pressure cooker since they're PP5.

These PP5 bead cups work well as reusable Petri dishes. You can use them for no pour agar, and they eliminate the need for parafilm. Sturdier than condiment cups, and less plastic waste. It's an economical and eco-friendly alternative. They are slightly more opaque than regular plastic Petri dishes, and I would suggest using food color in your agar for better contrast and clarity. Overall I am very pleased with them.UPDATE: The clarity is fine without any food coloring. They're airtight and have become one of my favorites.

Finally a fairly priced option for these. If you are looking for the adapted screw top Petri dishes, this is them. And for far less than the previous vendor that keeps jacking the prices up, and for far fewer items. If this vendor maintains this price, they will have a stack of cash in short order.These are PP5 on both the tops and the bottoms. They do just fine in PC Sterilization. Clear enough to see any culture you are growing easily. Absolutely perfect for "No Pour", petri dishes. I will be ordering many more of these in the future.

I used these for my Lion's Mane, Reishi, Blue oyster culture dishes. Not traditional use but works well and can handle being pressure cooked!

Use as reusable solid media plates. Plates don’t dry out, don’t appear to require parafilm (haven’t noticed contamination issues). They do become less clear after autoclaving. No issues with caps and bottoms working together.

I got exactly what I ordered

Good items, this is my 3rd batch. But this one some of the lids are too tight. They arnt standard.

Great for no pour agar.
