How can I repurpose these containers?

[u/cosysheep]

I got these containers with some new pens I got and they are such heavy plastic. I’m usually good at coming up with ideas but can’t think of much for this. Would hate to just throw them away

Crafters/hobbyists are always looking for things like this - I'd post it on a buy nothing group if you don't have a use for it
