Cricut Cartridge Storage Box

I have one of these storage boxes and it is compact & light. It comes with stickers you can apply to the outside of the box with labels of the enclosed cartridges, but if the boxes were, say, clear acrylic instead, then you could see the cartridges inside, which would be very handy. Also, these boxes only hold the cartridges & keyboards. Sometimes, it is nice to have the books handy for figuring out complex cuts, etc. so it would be nice if the box would hold these as well. Finally, I find that the plastic insert that holds the cartridges falls out from time to time. The cartridges stay in the tray, but the tray won't stay in the box. For the size & price though, this is a good product.
