This is a Da Vinci system organizer. I bought it about 10 years ago and used it for a total of 2-3 years. Photo 3: It has pen holders on both sides, which can prevent the organizer from opening when closed if you insert a pen. The holders can be stored away (Photo 2). Photo 7: There are ink marks from a ballpoint pen. Photo 8: There are binder marks. I used it with care and regularly maintained it with cream, so I think it's generally clean. Although there is a sense of use, there are no cuts or scratches on the leather itself. The binder mechanism works without any problems.
