Light up your building centre with translucent building planks. These planks are designed to be stackable in all directions. Construct on top of a light panel for added fun. Each plank measures 4.6" x 0.93" x 0.3" (11.75cm x 2.35cm x 0.8cm). Comes in 4 translucent colors. Use the Octa-Joiners and slot the planks in to create new angles and even a 90-degree angle for more secure constructions. Set of 200 planks and 20 Octa-Joiners all stored in a reusable plastic container. Grades PreK+.
