Versatile culture PET plastic cups with tightly fitting lids are useful for multiple things.
At Sans Vertigo we use these for fruit fly cultures and raising mantis nymphs.
The lids come without ventilation, but can be easily poked through with thumb tacks and pins. We recommend using small safety pins to make holes slightly smaller than 1mm, as it works well to keep smaller critters like fruit flies and gnats from going through.
Size: 92mm diameter and 110mm height.
Notes: Non-microwavable. Avoid use with hot materials.
