Too big & too thick for my purpose; emery surface does not last long - 2.5 stars [SEP] I do not care for these emery boards. There are 16 to the package and the boards are triple thickness compared to the standard personal-sized ones I am use to. However, the gritty surface on mine started to wear off after a few swipes of my nails over the board. Emery boards in general do not last long; however, the size and thickness coupled with the limited longevity makes me not like these. They do file the nails but they do not last.
