Open Ring Notebook Opuno Semi B5 30 Sheets

The central ring, which is easy for your hand to touch, is soft and flexible, allowing you to write smoothly even when the notebook is open.
●To open, hold the circle on the leaf and gently pull diagonally up and down to open the fastener.
When closing, pinch the top and bottom rings (three each) together. (The rings in the middle do not lock; they simply overlap.)
*JIS standard binder notebook leaves cannot be used.
