From the desk of the product designer:
Behind the design
“We started with a pretty small lock design, close to the size of a door lock. But at that small scale, the lock just didn't feel that satisfying to build, and the tiny pins were difficult to handle. So we sized everything up to make a jumbo-scale lock. This had the added benefit of making it easier to see how the locking mechanism works.”
