The Puzzle Combo box is one of my earlier designs, and it sports a combination of 1,012 possible keys.

This unique puzzle book was one of my first puzzle boxes that helped launch my design and manufacturing business. I designed this puzzle book as a puzzle for beginners, and when I produced it a few years later it quickly sold out.

This was the very first puzzle box I created, and this is where it all started. I made the first when I was about 14, then came back to the design a few years later and posted it online. I was amazed how quickly it sold!
