But they do erase well before they break part after a few uses .

These are the best that erase well.

The pink ones dry out and don't work as well.

I use them instead of the pink erasers that get hard over time, don't erase well and leave smudge marks.

These little guys erase well and are good for carrying in my pocket.

and I can stop carrying the block, they work just as well.

They erase well and don't leave any

No eraser erases as well or as smoothly as these erasers do

They erase well but are too soft and break easily

I'd say these caps are *almost* as good as the Magic Eraser blocks.

easy to carry, helpful, very good.

No smears, good erase, fit well in the hand.

They erase well - don't have to tear up the page to get the pencil mark out.

I've been spoiled by Pentel Hi-Polymer erasers (no other eraser works as well)

The Pentel Eraser Pencil Cap version of this does not work as well (you would think they'd be made of the same material, but maybe not, however I still use them for my pencil ends), so I recommend these blocks instead

They work great with both 0.7 and 0.9 lead (I use mechanical pencils) but I'm sure they'd probably work just as well on the regular number 2 wooden ones

I like the small size as well.

It erases so much more cleanly than any other eraser I've ever owned and it continues to erase well even after heavy usage

If you erase a lot, the small size of these would probably not work as well, and you may want the normal sized ones

We've always just gotten the cheap ones from the store, but those bend and leave crazy eraser marks on the paper and don't erase well at all

The erasers fit good on a pencil and leave not marks when you erase.

They erase well and seem to be holding up on the end of my pencils.

and now my kids love them as well.

It is not crumbly at all and erases well.

I bought these to put on the ends of my mechanical pencils and love how soft the material is and how well they erase without damaging the paper - but the dont tear at the cap edge (like some others Ive used).

erases well and doesn't leave much mess or pencil marks

Shopping at Amazon is so hassle-free and with Prime, it;s really fast delivery as well.

I've never liked these as much as Magic Rub erasers but apparently Magic Rub has changed their formula and isn't nearly as good as it used to be

I have been a student for many years, and I have never used an eraser that works as well as these

its so small and cute its easy to use but because it's small its easy to lose as well but its definitely worth the money

Soft eraser, fits my pencils and erases well.
