We have experimented many times that 307 PCS is enough to build the whole scene, but in order to avoid the trouble of being unable to build a complete amusement park due to losing blocks, we prepared extra 50 PCS blocks (357 PCS in total) so you can build the scene without any worries.

Our building blocks not only provide the shapes and colors of classic building blocks, but also uniquely shaped blocks such as marble runs, windmills, swings and Ferris wheels. These special blocks are expensive to produce, but make the building sets much more fun to play with. ► Compatible With Other Major Brands: Our building blocks are 100% compatible with the big building blocks, baseplates and building tables of other major building block brands. ► Includes Baseplate: Baseplates are extremely critical to allow you to build big building blocks.
