this review title is: great mini size grit does not last long and the content is: prosthe patterns are eh some suck and some are decentcons the grit wears out very quickly faster than a regular cardboard foam emery board that sucks i was hoping that the glass version was an option that would be more durable and last longer but sadly it is not i would say within a week i had worn both sides down on at least of these so it is now just smooth glass in those spots i was willing to make an investment on something that was longer lasting and potentially more eco friendly than buying the cardboard foam ones all the time but i will have to go back to the cardboard foam ones until i find something more durablethere is no way that throwing away that much glass every weeks is better than using cardboard foam.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
