What are the cardboard boxes in my Brick Me kit meant for?Updated 2 months ago

We call these boxes flatpacks, you won't receive one for every color included in you kit, however the ones you receive can be used to temporarily store your bricks once you have opened a pack, this is so you can store them safely and not have to put them back in the bag. We recommend to start by choosing two to three colors and filling up all baseplates that require them, then moving on to another set of colors and so on until you are finished building the whole mosaic.
