Sorta Journal

Sorta is the patented compact journal notebook that opens to let you rearrange pages however you wish. Notebooks are 8.5" tall, 6.25" wide, and 0.5" thick. Recommended capacity is 5 to 50 sheets. 
 
Sorta Journal - a notebook/binder with removable, rearrangeable, customizable pages. Sorta offers a number of notebook styles, but the interesting thing is that the paper is always removable and swappable, so you can put grid paper in for diagramming and lined paper in for taking notes in a talk or meeting. You can even combine them, so it's like carrying multiple notebooks in one. The Sorta is a bit of a combination between a binder and a traditional notebook, and brings the best of both worlds to the table—it's small enough to carry around with you, but flexible enough that adding and removing pages is easy.
 
HOW TO SORTA:
 
First, bend back the covers to open the spring-loaded spine and release the paper. 
 
Add, remove, or rearrange pages however you see fit.
Hold the spine open with one hand while gently sliding in the paper with the other.
Release to finish.
