I LOVE THIS!
This is such an amazing organizer and well worth the price.
Each row of compartments has an easy to use lock on the end. This ensures that the lids will not just come open. It has been really great for taking all my little embellishments with me to crops. Also, is a great space saver.
I have three of them now and use them to oraganize all of my brads, eyelets, snaps, buttons, beads, and misc. embellishments.
