Pentel Hi-Polymer Ain Eraser Small - Black

I recieved this eraser today and thought I'd share my initial impressions:

After more than 30 sketches today, and a good deal of erasing for both correction and toning, I've found this to be a very usable eraser if somewhat smaller than I was expecting. On the other hand, compared to the MOMOs I usually use, it's not that small.

Dust:
I tend to work with a very light hand and while this block produces more dust than my other Pentel (round click-stick eraser), it's not any worse than my previous experience with MOMOs. That being said, I just killed off my last MOMO and thought I'd try these instead of just going with what I've always used. I'm planning on getting more with my next order so I thought I'd do some side-by-side comparisons and do my best to remember to write a review.

Erasing:
This is where this block really seems to excell. It seems that it takes half as many strokes to erase a mark compared to my MOMO but I won't know for sure until I've had a chance to get some more MOMOs and do a SxS comp.

Consistency:
This block feels a bit softer than I remember the MOMO being. In spite of that softness, it doesn't seem to wear out any more quickly. The nice part of the consistency is that it feels like it does a better job of grabbing the paper without wearing away at it... if that makes sense. It seems to slide over the paper itself without too much abrasion, but the softness makes it feel like it's getting a good hold of the graphite.

Toning:
I've only used it on graphite so far but it's done a good job. The performance is uniform without any unexpected snags so I can say that the manufacturing seems to be quality. (Now I wish I could say that for my last batch of kneeded erasers, but don't get me started.) Since this block's already black, I'm not sure if there's any loading going on but even after a lot of work which would typically load any of my previous white polymer erasers, this block is quite satisfactory.

I'll have to save performance with Prismacolor pencils and charcoals for the next time. HTH....

Ain vs. Uni-Ball boxy= UNI-BALL !
I feel like the Ain is a copy of the uni-ball, even thought it's cheaper, does not last as long!

This eraser is terrible and awesome!
Good: this eraser erases very well and when you erase it, it feels very smooth:)
Bad: when you erase very dark 2B lead or higher, the eraser smudges it all around and you have to go back and erase the marks and smudges. It also leaves a lot of shavings. It is just like the eraser pink pearl but a little better. I don't recommend this very much but...... I would highly recomment the black Boxy eraser.. It is more expensive, but is is worth it. It lasts a long time and it is VERY SMOOTH when you erase something. On the other hand, this eraser feels like you are pushing across the paper that doesn't want to be pushed and causes a lot of friction.

smaller than i thought but good eraser leaves small amounts of dust

This eraser erases very well, but it leaves a lot of small shavings. I still gave it five stars since I am not one of those super-picky people that cannot stand to blow pencil shavings off of my paper. The eraser itself does a wonderful job, and I cannot complain.
