Kokuyo KadoKeshi Stick Mini Twist Eraser - Lime Green

In geek terms, this is a 1-pixel eraser. If you're erasing half the page, use a "flood fill". But when you really, really need to get in there close, this is perfect. There's always a sharp line or fresh corner waiting for you to rub it down. Some have said it doesn't erase well, but I haven't had that experience. I erase only small marks on sketch paper made with Hi-Polymer lead, though. That can make a big difference. For me, this chibi is an essential tool, even if it leaves a lot of mess behind.

The Pros: This eraser is super kawaii. It comes in great colors and looks like a tube of lip balm. It's also just generally a great design--you can twist out only as much eraser as you need, and the eraser has really useful points and edges that help with precision erasing.
The Cons: It's all form and no function. The eraser doesn't erase well and leaves smudges. It also tends to accumulate a lot of eraser shavings on the tip which detract from its precision, and are also just generally a pain to pick off.

I bought this eraser mainly based on how it looks, not its functionality. It doesn't erase as well as others, but is good if you just want to erase something small, like a few letters or words. If you're looking for a great all purpose eraser, this one isn't for you. It is really cute though and I always get comments at school about it!

I really don't understand how Kokuyo could have gone wrong with this eraser. It's a great concept, it's cute, compact, etc. etc. But it FAILS HORRIBLY when it comes down to erasing!

It doesn't erase well, smearing and smudging everything, and the rubber clumps together while sticking to the eraser. This little clump covers the tip of the eraser and it won't erase until you pick it off. It also adds to the smearing and spreads itself around, so the entire point of the precision eraser is gone!!! }:|

Eraser is really good for small errors and detailed erasing like on a drawing or draft.
