• BUILD BIG: Twelve 18 inch planks, ten 12 inch planks, and 14 connectors let kids practice their problem-solving skills as they create huts, houses, and hide-away constructions big enough to sit in or crawl through. Blocks and connectors easily interlock to create big, sturdy, stable structures.
  
• GET CREATIVE: Two oversized (10 inch x 18 inch) "toppers" add architectural interest like an arched entryway or crenellated roof line perfect for a dramatic castle, imposing fortress, or any other creative construction.
