You might need to take your spools with you to make sure that they will fit in the little compartments.
That's what I use! you can fit 1-3 spools per slot (60 slots per box) depending on the size of the spool. I would recommend getting a bag of those really large rubberbands and putting it around the box. That way when I drop it, they don't go flying around everywhere!
I have about 20 of them! You do the math ... I'm afraid to think about it.
