I've always loved office supplies. Back to school was always so exciting, with new notebooks, folders, pens etc. Everything would be pristine, unwritten in - it made it seem like anything was possible that year.
I also loved buying stationary as a teen, all different kinds. I still have some that I've had since I was in my mid teens, and I am 47 now. From thick paper with bold designs to dainty, super thin sheets with barely visible floral designs, I loved it all.
As for pens, I am not so concerned with brand, but for me they must be not fine tipped, and most important of all, they must be fat. I don't like using normal thickness pens, for some reason the rounder ones feel more comfortable in my hand.
Lastly, are you all ready to be jealous now? I work for the company that makes Post-It Notes. Our supply room is an absolute dream of every kind and color Post-It you could want. My favorite are the 6" by 4" lined note pads, preferably in blue. We also have all the fun dispensers, themed Post-Its and other accessories available at a considerable discount in our company store, which is just a couple flights of stairs below me. My actual job has nothing to do with the manufacture or sale of Post-Its, but it sure is a nice fringe benefit.
