The paper inside the notebook is waterproof, so you don't have to worry about ink smudging. The writing can be easily erased with the accompanying cloth, which means that I can reuse it indefinitely, something that I have never experienced before and find very novel.

The writing on the paper can be erased with the included cloth, which saves paper and is very eco-friendly. It is a new experience. The notebook cover design is also minimalist, which is a style I like.

The good thing is it comes with a cloth to wipe. But you have to wet the cloth first. If you close the notebook while the pages are still wet from wiping, they will stick together. It's also inconvenient that it takes a few seconds for the ink to dry. Otherwise, it may be a mess. The OCR is like magic and I like it actually. Also, don't press too hard on it when you write because it will leave a dent.

Love it!!! A gift to my friend who is an environmentalist and he likes it a lot! The cover feels elegant and the paper inside is thicker than normal paper. Pens of three colors can be brought with the notebook everywhere. Write down my ideas anytime. Very convenient. But be careful don't touch the writing quickly. Give it ten seconds to be ready. Easy to erase and with a cloth inside. Will buy one for myself.
