SURUKOTO (する事, meaning "things to do") is a to-do list pad built around one specific friction point: you have your list, but no pen. Marumo Printing solved this by engineering a mechanical check system directly into the paper. A small triangle tab runs along the right edge of each line; fold it back, and a green circle appears beneath, marking the item complete. No pen, no pencil, no phone needed.

The pages are perforated so you can tear out only what you need, and the sheet folds down small enough to slip into a wallet. The format, 80 × 210 mm, is intentionally narrow and tall, closer to a receipt than a notebook, so it disappears into a pocket without bulk. It works well for grocery runs, packing lists, and travel prep, anywhere you want a physical list but can't count on having something to write with.
