Using this Barbie Dreamhouse Building Set is super fun! First, take out all the 1795 bricks and pieces from the box. Start building the different rooms like the bedroom, kitchen, and pool one by one. You can use the included micro - dolls (1 Barbie, 1 Ken, and 2 fashion mannequins) to play with once the house is built. When building, make sure to follow the natural way the pieces fit together. If you get stuck, just take a break and try again later. As for maintenance, keep the set in a dry place to avoid the bricks getting damaged. If the pieces get dirty, you can gently wash them with mild soap and water. And remember, you can combine these pieces with other MEGA and Barbie building toys or even compatible toys from other brands to create an even bigger and more amazing world for Barbie and her friends.
