Recently my sons have gotten into Lego which makes me glad I saved all of the Lego I had as a kid. A friend passed this along to me and this thing looks great. It’s called a “Box 4 Blox” and it’s a sorting tray system. Like those old coin ones where you’d dump the coins in the top and shake it to sort everything through the slots, same concept. Dump the blocks in, shake and sort. No more running through a box with all the blocks in it just to find that 1×2 transparent green piece that you know you only have one of. Very cool stuff. Will definately be under the xmas tree this year because you know Santa likes organization.
