The Safe

Learn about the inner workings of machines from the inside out. Koontz takes its cardboard seriously. It's got a serious job to do. Before you shrug off cardboard construction as flimsy and incapable of mechanical functionality, take a look at what you can do with Koontz! Highly durable, recyclable cardboard is the basis for every Koontz toy. Follow the instructions to create the inner workings of a combination lock used in safes. Did you know each lock on a safe is a puzzle? Open a combination lock from the outside and it looks like the random twisting and turning of a dial. Look at what happens on the inside while you are twisting and turning the dial – and find supreme satisfaction in the ingenious engineering. Build a Koontz Combination Lock following the step-by-step instructions and fun activity book, and you'll earn real respect when you show friends and family how it works.
