✅【Carefully Selected Genuine Materials】 "We want you to cherish this for a long time." With this in mind, the craftsmen have been meticulous in their material selection. We have chosen durable grained leather for the material. While sheepskin and synthetic leather are prone to scratches and require frequent maintenance, grained leather is scratch-resistant and less prone to showing scratches, so you can use it roughly every day. Even if you are busy, you won't need to do any troublesome daily maintenance. In addition, because grained leather is highly durable, it will develop a rich patina over time, becoming a notebook cover that is uniquely yours.
✅【More than just a notebook! Convenient pockets that hold lots of things】 For those who want more than just a notebook cover to hold a notebook, we've incorporated convenient features. 【Multipurpose space】 You can store small items used with your notebook, such as rulers and Post-it notes. 【Business card and card holder】 We've designed four card pockets on the left and right sides. By storing business cards and credit cards, you can respond smartly in case of emergencies. The card pockets also have RFID protection, so you can rest assured about security. 【Pen holder】 A pen is essential for notebooks and planners. Even thick pens like Frixion 3-color pens can be securely stored.
