LEGO Storage Brick 4 - studs Light Purple - Stackable Plastic Storage Box with Lid for Kids and Adults Ideal Desk Organizer and Toy Box - 5.6L Capacity

Works great to store Lego or duplo blocks, or anything that will fit. It is a bit pricey for being a plastic container, but you pay for the brand and child recognition. It is cool that they are effectively Lego pieces themselves, so if you buy more than one, or in combination with the larger sized one, you can stack them/build something.

We bought a giant pack of Legos at Costco and all of them fit inside of this!

I’m happy, good product.
