Great with reservations (13 July 2010)
This is that really hard plastic that my mom always called Styrene. I don't know if it's really that stuff, it just feels like it. The lid is a little fiddley it opens on tracks and it's kind of easy to pull off it's track. Now, that being said, they are the right size and shape to hold loads of cricut cartridges and booklets with overlays. They truly are just right. How well they hold up and how well the top works over time, we'll see. I'm glad I got them (I got three of different color lids) and will try to use them to their full extent.
