Pentel Ain Clic Knock Triangular Eraser with Clip - Metallic Blue Body

I want to like this eraser, but a couple of flaws keep it from being a favorite.
The triangular shape should allow precision erasing, but once you've worn a corner down, the precision is lost. After a few erasures, you're left with a big round eraser.
The mechanism doesn't hold the eraser in place well, so direct pressure will push the eraser back into the body. Side-to-side is okay, but combined with the above, it loses the precision the triangular shape could deliver.
The eraser itself is good, not abrasive at all, and very effective. I don't find the shavings to be sticky or hard to brush off, and HB markings are 98% removed. If the clutch could hold the eraser in place better, this could be perfect.

wow, using this compared to my steadler mars eraser stick, is so much better, the eraser isn't crumbly and it removes my pencil marks with more ease, i would definitely recommend these :D

It has a superb quality. Erases clearly and neatly. Perfect for young artists.

In response to a couple of previous reviews regarding crumbs/dust sticking to the paper:

I've also noticed this happening but I've found that lightly pressing the eraser to those clumps lifts them with almost no effect on any graphite that might be under those crumbs. There is some but I'd have to break out a loupe or magnifying glass to notice.

On the other hand, I tend to only do non-"production" sketches so I might not be the best authority.

For me this eraser works very, very well and is (in my opinion) a step up from the round click-sticks by which I used to swear. I like the shape much more since I find it to be much more versitile.

Just my opinion. HTH.

Its great as the eraser dust sticks on the paper...
my fan won't blow away then... NICE!
In terms of ergonomics, aesthetics as well as funtionality...
