One of the prototypes I was most anxious to get in my hands from Jeffrey is our three plus one case. This design has three slots for pens on the left side (it can hold more than three as seen in the picture below) and a single memo book (3.5" x 5.5") sized pocket on the right. It can actually fit two memo books with ease. The simple bi-fold design gives you easy access to all of the writing tools you need.
There is still some tweaking to be done on the final dimensions but it is looking great so far!
