I'll get some more boxes then
I don't have a house. I would buy maybe 12 if I had a house and workshop.
Well - it's just something to be aware of if you are a person who like organization to help you find stuff later; I tend to be this way to a great amount - I believe that everything should have a well defined place, and it bothers me when stuff isn't put away in the place it was originally at. I know not everybody is like this, though.
The nice thing about such boxes, though, is that empty they nest easily inside each other, then stack all the lids on top of the nested stack, and its fairly compact.
Oh - one other thing (especially if you have a bunch of the same boxes) - a label maker should be used to label your boxes (and, depending on how or what you are storing them on, you may want to make labels for all four sides, and possibly the top as well)...
