It's a well designed play set. The little props are well made too. I bought set A from another place since it was out of stock here, both sets can be hooked up with each other without any issue, you can even stack them to make a 2nd floor if you want! The walls are in fact very durable and very easy to put up together without you worrying about breaking them. The set also comes with a pack of stickers that helps the props sticking to the dining table or the ground.
