Purchased this set to give shop a try before considering purchasing more expensive sets. This set exceeded all my expectations. Bricks are sturdy, well made, and interchangeable with Lego bricks. Instructions could use a tiny tweak for added clarity, some of the photos weren’t clear about placement or if the single pieces were the ones with or without holes.
Bricks were divided into 8/9 bags that were divided into 2 bags labeled 1 or 2. Had to open all bags marked with 1 in order to access all pieces as needed to build book first. Then had to do same with all bags labeled 2 for castle. Be prepared to have bricks all over your floor/ table until set is built.
Shipping was quick, shipped from China warehouse to Canada.
I will be purchasing more sets.
