The Overtime box is a multiple step box that is likely to challenge the best of puzzlers. An innovative design that would result in a very challenging, yet fun and attractive box, with enough durability to withstand a typical Escape Room environment. No puzzle box can tolerate excessive force, but this one goes further in that regard that any other I have seen. Note that no force at all is required to solve this. Fingertips and brainpower are all you need
The box externally measures about 5.2 x 4.2 x 3.4 inches (not counting the dials which extend another .75 inches from one side. Internal space for inserting something is about 4 x 2.8 x 2.3 inches. The internal space has a felt lined bottom.
