I absolutely adore Lihit Lab Teffa Bags. I started with the 2 way bag, then
added the pen case and A5 bag, the A4 bag was the last one I purchased (I had to
wait for JetPens to restock). Although the color says 'Black' it's actually a
dark gray. I was originally using this bag to hold paper documents, a small
notebook, a pen and a highlighter but then I realized that my 13 inch ultrabook
fits in it like a glove! And the charger fits in the front flap compartments!
I now use it for my laptop case.
