the files are great but the buffers [SEP] the files are great because they actually work but the buffers do not work at all i got this just for the buffers because i never had one and wanted to try them out the blocks seems like they are just blocks of foam and they have this hard coating on to seem that it has grit but when you try it on your nails it does not even work at all i thought that it was just for one block but nope it is all of the blocks it also has this weird smell and when i tested them out i guess some of their coating came off overall get if you want the files but just toss out the buffers since it is no use
