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.
