The Manicare Nail Buffer 4-way is a whole manicure in one tool pretty much.
It has a step by step process which I think is really useful for knowing you really have done your nails in the right order or if you're a manicure novice.
The side I was least fond of was the emery board because I prefer a smaller emery board that can get around the nail a bit more. Other than that I found all the sides really good and they certainly did what they claimed to do. After using this tool my nails looked and felt shiny and revitalised.
If you don't want looks of different nail tools hanging around this is the perfect tool for you.
i have collected many of these over the years, get used by all the females and often the males in my house. great for strengthening your nails and making them so smooth and shiny. great to use before applying nail polish
