Kokuyo Mirikeshi Star Multi-width Eraser

I found out about this gem through a YouTube video and had to try it out for myself, so I bought one. It's an incredible eraser, and I'm disappointed that more erasers aren't made this way. It has a very intelligent design that makes it great for erasing any size mistake, unlike the more standard rubber and kneaded types. This was probably one of my best recent purchases. The note and stickers that came with it were a cute bonus, as well.

Very nifty even if you have to pay importer prices. Especially useful for correcting precise graphing errors.
