This is a 2026 wall calendar from Hewlett-Packard Japan, Ltd. When closed, it's an A4-sized booklet, and when opened, it's A3 size for hanging on the wall. The top half features beautiful landscape photos, and the bottom half is the calendar. It's a slim and very easy-to-use calendar! I personally recommend it. I have multiple of the same item, so bulk purchases are also available. Brand new and unopened. I plan to ship it on the same day or the next day.
