This is a case of 300 plastic petri dishes.

Plastic Lab Petri Dishes are guaranteed sterile if ordered in 10 or 300 packs - perfect for laboratory culturing use.

Petri dishes are also great to use with dart frogs as an egg laying surface. Simply place half of the petri dish underneath a coconut hut, and your frogs will lay eggs on the petri dish's clean, smooth surface - they think it's a leaf! Make sure to keep any unused petri dishes clean, or your frogs may not utilize them!

This box will contain 30 - 10 count sleeves.
