The Bauspiel Fairytale Windows add an extra special element to play. This set includes 12 alder wood window blocks, in six different block shapes - cloud, semi-circle, triangle, arch, rectangle, and hill - contains one to two see-through "jewels" in its centre.
 
The gems invite children to discover light and the myriad of effects it brings: place them on a light table for a glowing array, near a window to shine a rainbow of colours over the floor.
 
Bauspiel Window Shapes are the perfect addition to a building block castle or house, forming oh so pretty windows, portholes, turrets, and rooflines. They turn every castle into a beautiful piece of architecture.
 
Each shape has a flat base to enable stacking by little hands.
 
Packed in a wooden tray. 
 
Difference with Sparkling Roof  : Fairytale Windows are two-sided, transparent and see through, while Sparkling Roofs are one-sided, sparkling but not see through.
