A smart eraser designed for highlighted notes
Mirikeshi is a 5‑in‑1 precision eraser with five different edge widths: a pointed tip plus 3 mm, 4 mm, 5 mm, and 6 mm sides. Each edge is sized to match common notebook rulings, so you can choose the edge that fits the line you’re working in:
- Point: single dots, tiny details, fine strokes
- 3 mm: small letters or narrow ruled lines
- 4 mm: 4–5 mm grid and many planner boxes
- 5 mm: standard B‑ruled notebooks
- 6 mm: wider A‑ruled notebooks and headings

When the edges become blunt, you can simply slice off a thin layer with a knife to reveal fresh, sharp edges—so Mirikeshi stays precise for a long time. The width numbers are moulded all the way through the eraser, so they don’t rub off as you use it.
