How to storage mini figure’s

So myself as a CMF collector.I have purchased over 300 mini figures until now and it’s being a mess in my house because u don’t know where to put it.Once I was in flying tiger a Dutch department store for good price.I found this box which is perfect suitable for mini figures it’s 1 euro.

It’s a white box and it’s called:”opbevaringboks storage box”It’s very easy to stack them and put on ur table when you need the mini figures
