Todo-lister / awesome todolist guide - transform anything into a todolist :D

Transform anything into a todo-lister with the TodoLister v3.
The leap make it easy to user on any kind of paper / book / notebook
Thin enough to be in any backpack or desk, strong enough...
Can be used with ballpen pencils and any king of writing material.

(first version had no leap... second version holes were too small, this is the perfect one, use it everyday)
