not really good enough for acrylic i was hoping they were similar to another brand that looks like them [SEP] just ok i got them for a cheap price if i had paid the current price i would not be happy as they are not good enough to use on acrylic or hard gel nails i was hoping they were similar to another brand the picture looks kind of like them but when i got them they do look totally different these are good only for manicures pedicures the grit is very fine not at all not what i wanted but you get what you pay for
