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.

this eraser is way too pretty i want all of the supplies sooooooooooooooooo badly

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

it's a decent eraser for small areas but not for large ones. The amount of corners on it is nice for getting small places and, if you're into cute things, it looks really nice hanging from a pencil bag or back pack.
It was a bit anoying to work with though. I kept feeling like I was going to break it or that it wasn't sturdy enough to take the pressure needed to get things really clean. Also, I couldn't do large areas with it. just smal tiny areas. Any more than tiny touch ups and the eraseing stopped being so clean.
