The Iron Resolve of the Golden Owl is a one-of-a-kind hand-bound binder-book. The front and back covers, along with the interior are chiyogami and washi papers, bound with book canvas. The interior binder clip holds 2-hole punch A5 paper. I’ve been using a similar one - without cover artwork - as a gallery guest book for years, and it’s held up wonderfully. While I wouldn’t suggest using this one the same way, it’s a testament to how hardy these books can be.
