It is a passport-sized unlined notebook refill (003).
Since it is pure white paper, you can write, draw, paste, paint, and use it freely without being bound by the frame.
Since we use original writing paper (MD paper) that is particular about ease of writing, it is difficult for fountain pens to bleed or strike through.
