I've been using this nail buffer for a few years now & it really is one of the best I've tried! I've tried the Orly 3 way buffer & the dead sea 4 way buffer - both of these are great but do not compare to the manicare one!
The block is firm but flexible and is nice to hold, all sides are marked clearly & numbered so you know which order to use them in.
They leave a beautiful shine on the nail that lasts a couple of days & preps the nail for perfect polish application.
I have two of these - one at home and one in my handbag. Great for prepping nails for polish. I love how shiny and soft my nails are after using it, so much so that I can leave them naked. I've had them for 2+ years now, and still in great condition - other buffers I've had started threading within months.
