This is a cover for the Hobonichi Techo Weeks. The Mega version can also be used without issue. I purchased it from the official website, but I never really got used to the Weeks size, so I haven't used it much. However, it's not in perfect new condition, so please refrain from purchasing if you are sensitive to this. "If I could carry multiple pens with my planner..." This cover was planned with that in mind, so it has plenty of pockets and storage. Leather is used in parts such as the zipper tab and tag, giving it a high-quality feel. Please see the Hobonichi Techo website for details. https://www.1101.com/store/techo/ja/2026/sp/detail_cover/wc25_tragen/ This item will be shipped via the "Nekopos" delivery service. Thank you.
