Review on Jonti Craft 8020JC Cubbie Tray Black by Stephen Tharpe

This is exactly what I expected. They are well researched and well done. It's worth noting that black is a few dollars cheaper than other colors. If you don't like bright colors then these are for you. I put a label at the end with the color of the dots representing the levels of the books I keep inside and that's enough. I have some yellow, blue and red but they were inherited from another teacher. I'm just as happy with the black ones and they saved me a ton of money.
