The WG-PN1 is a little e-ink notebook sold in 2019 in Japan. I was able to buy one online and get it shipped into the US.
I've been using this thing to keep track of my schedule, to-do lists, and for general note-taking. So far it's been very good and the battery life is fantastic. Plus it has no internet connection! If you're like me, you might find that appealing.
Since Sharp only sold these devices in Japan, the UI is displayed in Japanese. I don't speak it, but a few pieces of it are in English for some reason which means I can get around the language barrier decently well. Plus, my girlfriend speaks Japanese and she helped me figure out where a lot of stuff was. Shoutout to her :3
The touchscreen is capacitive e-ink and it came with a stylus and a notebook-style case. Small, fits right in my pocket! Accidental touch rejection is good, and it does feel good to write on.
This notebook is the last of Sharp's Electronic Notebook series, and the only model with USB-C charging and an e-ink display (other models had micro USB and LCD displays). There's a NeoCities site that goes over these devices in great detail.
I have noticed the power button is a little vague, sometimes it takes multiple presses to turn the screen on or off. If I use the stylus to press the button, it works fine. Not sure what's up with that.
