PP press cap containers 365ml

These are the containers we are using for multiple uses , from breeding meshed containers to subterranean traps, and also these are the containers we have in our Winklers and Conical beating sheet as collecting containers.

Here are sold plain with full cap not very good for collecting on fields as the press cap doesn't seal well, they can suddently open in your bag

But despite this trouble they might have these are perfect used for breeding insects which need humidity, these containers are also used for keeping under liquid lots of insects, they can be overlayed on each other to save space and be used as pitfall traps.
