This notebook allows you to digitize any notes taken by hand—and it’s only $20

Write, scan, erase, repeat—now at 25 percent off MSRP.

While digital note-taking is certainly convenient, the physical feedback of pen on paper is impossible to replace. With the Rocketbook Reusable Smart Notebooks, you don’t have to make a choice. These smart notebooks allow you to archive handwritten notes in the cloud, erase all the pages, and start again. You can grab one now for $19.99 at the PopSci Shop.

Just like Peter Parker at school, you would never know that Rocketbooks have superpowers. The pages are made of high-quality paper, and you can write on them with any pen. Using the companion smartphone app, you can scan your notes in seconds. A list of symbols at the bottom of each page lets you select where you want your scribbles to be stored—Google Drive, Evernote, Dropbox, and so on.

But the real magic happens when you use a Pilot Frixion Pen—you know, the ones with ink you can rub out? Once you’ve filled your Rocketbook and archived the important notes, you simply place it in the microwave to erase all the pages and start again.

They’re normally $27 each, but you can get your Rocketbook now for $19.99.
