The Hobonichi Weeks Clear Cover is a protective plastic covering that safeguards the Weeks planner from daily usage. In addition to safeguarding the planner, the Clear Cover also serves as a convenient bookmark, pen holder, and pocket for up to two cards. The Clear Cover is a great way to personalize the Weeks book with photos or decorations for an even more enjoyable user experience. Unfortunately, this Cover is not suited for the Hobonichi Techo Weeks Sneaker, as their sizes are not compatible.
