With your math brain on, you've just written out your 10-step solution to the latest puzzler. But to your dismay, you find a mistake in step 3! You must erase steps 3-10 and start all over. You grab your Matomaru-kun and erase. With this soft eraser, not much pressure is needed to erase cleanly. Best of all, the shavings gather into neat clumps, so you are not left in the end with a dust bowl of eraser shavings. Some clumps stick to the eraser, making it even easier to pick them up and throw away. Because little effort is needed for erasing and clean-up, you can spend all your energies on re-tackling that math problem.
The name says it all for Hinodewashi's Matomaru-kun eraser -- "Matomaru" means "collects" or "gathers," and the eraser shavings do indeed gather neatly into clumps for easy clean-up, leaving you with a clean desk.
The eraser is available in a variety of sizes and forms.
Dimensions of one eraser: 1.2 x 0.6 x 0.4 inches (3.0 x 1.6 x 1.0 cm)
