Handmade M5 size system notebook, simple, Tochigi leather Last one available This is a self-made M5 size binder (system notebook). The size is approximately 130 x 180mm when open, and the金具 is 15mm, so you can hold plenty of paper. *The leather used is 2mm thick nubuck leather, precisely cut and lightly polished with mink oil and Tokonole. There are scratches and marks unique to leather, for those who can enjoy them as character. *A simple protective part made by cutting a clear file is attached to prevent ring marks on the binder. (Protective parts can be removed) *The binder金具 can be removed with a screwdriver because it is screwed in. *Self-made refills and lifters are included. *Because it is thick leather, it may be stiff to open at first. Please try to find ways to improve this, such as using a rubber band.
