We’ve been showing you a lot of covers for Moleskine notebooks, but now it’s time to show you a notebook that makes the chemistry major in me salivate. This set starts with the Levenger Notabilia Notebook, which is like the one I used to document my lab research. It’s 7 3/4″W x 3/8″D x 10″H with 140 pages of 90-gsm weight paper with a 1/4″ rule. The notebook is sewn together instead of glued. The smooth, full-grain leather cover is 8 1/4″W x 1 1/4″D x 10 5/8″H. The cover is available in black or red (the brown shown is no longer available). The Notabilia Notebook with Leather Cover is $99. You can add your initials for $6 extra or your name for $12. You can also buy refills of the Notabilia Notebook for $22 for two notebooks.
