This is a "revolutionary" open-closed signboard that combines interesting typographic tricks and a gear mechanism.
Just rotate the handle, and open and closed switch in a magical way.
The first thing that will impress you is the beauty of its structure. The many parts are meticulously calculated and assembled to form a unique shape. 
This is not only a mere piece of invention, but rather a practical contraption.It is more convenient and quicker to use than traditional signboards.
It's easy to operate and solid enough to withstand daily use. 
This is also a toy that can be enjoyed by both adults and children. Just watching it move is oddly satisfying. It can be an educational toy that allows children to learn how gears work while having fun. 
A revolutionary open-closed signboard that everyone can use.
