I have a huge supply of office supplies and during my yearly clean out, I noticed the abundance of erasers that I have. A majority are dollar store erasers but a few are the white staedtler brand! This is my favourite brand of erasers, I have never gotten smudge marks when using them, I don't need to apply too much pressure (which can rip my paper) and they erase very smoothly. In school I was always given the long, thin, pink erasers that did the complete opposite an vowed that I would never purchase those pink erasers again! What erasers do you find reliable?
