Pentech Lead/Ink Combo Erasers 2ct (27524)

I am utterly appalled by the ineffectiveness of this product. I bought this product because I always have to write in pen in my class. Unfortunately, this eraser does not erase pen at all! I think I spent approximately 10 minutes rubbing over a word I wrote in ink. Nothing erased. I just ended up tearing up the paper. I then tried this eraser with 5 other pens and it still would not erase anything. Since I bought 4 of these erasers, I ended up trying them all and none of them worked! All this vile eraser does is erase pencil. Disgusting. Don't waste your money on this mundane eraser. You'll feel like you are betrayed if you do so. My true rating for this lousy excuse of a product is, in actuality, negative infinity, which is unfortunately not applicable.
