The Rocketbook Everlast line of reusable notebooks are reusable notebooks with an app that lest’s you scan handwritten notes to many different locations including OneNote, Everlast, Dropbox, Onedrive, an e-mail address, etc… They’re like small whiteboards that allow you to easily take notes for whatever you want, and then have it filed away exactly where you need it to be.

Executive size is the one I like. It’s 6″x8.8″.

There are also the Letter 8.5″x11″ and pocket 3.5″x5.5″.

These require you to use Pilot Frixion pens and markers:

You can erase these with a damp cloth or paper towel. There are also cheaper microwavable versions, but they only work a few times per page.
