I hope those were steralized after they were used by the researchers. 😀
Seriously, they do look great for holding small pieces. I have been searching for some time for a good storage system. I would love to find a tip bin system (Northern Hardware has some but they are ungodly expensive). I currently use Lego Blue Tubs (like from tub 3033) for all my standard brick, clear shoeboxes for specialty pieces, and hardware drawers for small specialty pieces. The tubs stack nice but gets messy and crowded when I am working with multiple colors.
I was thinking of getting some of the sliding clear drawers from Walmart/Target but I need drawers with sturdy internal dividers (do those have good internal dividers?). I am also considering building a custom storage system.
