Absolutely essential.
I've ordered many Czech glass file sets from bona fide beauty and love them all. I have also recommended them to many friends and family who have also purchased from bona fide beauty and love them. Outstanding quality products and excellent customer service!<br /><br />I keep this foot file in my shower and use it at least twice per week. I start with the grittier side, then use the finer side. Even during the summer when I am wearing either flip flips or barefoot, it keeps them looking great! It's never too rough and rinses clean easily. This is a must-have product for me and I've ordered a couple backups in case it gets dropped and broken...and it should be noted it's been dropped multiple times and has survived thus far!
