[leashless]

https://www.westonboxes.com/ I recently discovered these. Lifechanging in two ways:

* you can put them on their ends and they don't fall over, which is ideal for storage on shelves

* translucent so you can see what's inside

Pull off the shelf, open up, rummage / sort / process (with extra space in the lid if needed) then pour everything back into the main storage from the lid and reshelve.

It's amazing how being able to shelve on their sides (rather than in a stack) changes things.
