To use these ZURU Max Build bricks, just take them out of the storage box and start building according to the ideas in the booklet or your own imagination. The bricks are compatible with other leading brands, so you can combine them with your existing collection. When you're done building, simply put the bricks back into the storage box for easy storage. For maintenance, keep the bricks away from extreme heat and sharp objects to prevent damage. If they get dirty, you can wash them with mild soap and water and let them dry thoroughly. Always supervise children aged 5 and up while they are playing with the bricks to avoid any choking hazards.
