There are marks from where I wrote with a Frixion erasable ballpoint pen in a few places. I erased them, but the marks are still visible. Please check the images. ※ See the red circles in images 4 and 5. Also, there are marks on the back cover of the planner that were there from the time of purchase. It shouldn't affect usability, but if you are concerned, you may want to refrain from purchasing. It seems to be a hard-to-find item, and I finally found and purchased it at a Daiso after visiting several stores, intending to use it. However, I found the size a bit too large for me, so I'm putting it up for sale. ⚠︎ Since it is not completely unused, please refrain from purchasing if you are concerned.
