These are actually really excellent quality, and if you are only storing singular 12x12s and embellishments, then you are set! I, however, really needed enough space to store 2 copies of Echo Park kits plus embellishments, and it wasn't quite enough room at the top near the zipper. They will still get used, but they don't quite serve my purpose. They would be perfect if you are storing leftover bits from an entire collection and still want to keep them together. They would also be wonderful for creating mini kits from your stash!
