Tropical Shine Colossal 4-Way Blue-Pink Buffer - Professional Nail File & Buffer for Shaping, Smoothing, and Polishing Nails - Compact and Portable Nail Care Accessory (707330)

I've been buying these since beauty school in the 1990s. Wow. 30 years? Yup. I'll be buying them for at least 30 more years, too. The four grits are the perfect step-down to a perfect, smooth, shiny surface on nails, stones, metals, plastics, paints, wood... Not so much on glass, obsidian, or opals, though. Anything really brittle (chippy) needs an actual lapidary with running water and diamond grits. But, for the rest of the world, this file can make it shine, shine, shine. Just make sure to start each color a bit heavy-handed and let up to barely touching before moving to the next one. Blue, then pink, then white, and then gray to buff up that perfect shine. If it doesn't do it, you rushed one. (Probably blue or pink. Just start over.) Happy polishing! :-)

Y'all, I have been using these Tropical Shine 4-way sticks since I was in middle school. My mom used to get them from Sally's and we'd lay across her bed listening to music and file, buff, and shine our nails. I love how these remove the ridges on top of your nails and the shine at the end?! Unmatched. I rarely wear polish on my nails because I love how this nail file keeps them looking so healthy and natural. I hope these never get discontinued, I don't know what I'd do without them!!

I hate nail files that are like sand paper with the sand coming off.These are high quality nail files.No sand comes off and its got 4 different textures.It also says its washable & disinfectable.Its a nice size without being too large. I highly recommend it. Wish they had more fun styles

These are the best 4 way nail tools you can buy. Very professional quality.

I have used these nail files for years and keep one in my purse at all times. I am not a big salon person and this file helps me keep file, shape, buff and shine on my bare nails. It seems that they are smaller than they used to be but they work great and last a long time. These are one of my favorite things!

These are GREAT! I couldn't be without one. You can even use the smoothest side (the grey) to polish your jewelry. I swear - no scratches and beautiful shine on my gold and silver. Doesn't take off any metal - just tarnish. Better than my lapidary buffer-that takes away metal too. Just imagine what it can do for your nails. Can polish up that scratchy lost it's shine last coat of nail polish instead of adding a clear coat. Or buff up those no polish nails and shine shine shine. They seem to last forever too. Don't ever use an emery board - they will ruin your nails. This one has 4 textures from Blue-rough, pink-medium, white-smooth, and grey-polish. I miss the round ones that you could bend to smooth the underside of your nails - so TROPIC SHINE if you read this - bring then back - please :)

I have been using these nail files for years. I find them good for shaping, nail ridges, and buff and shine

I discovered these at a home show in L.A. decades ago. My nails were recovering from porcelain treatments and this was the only solution to getting my nails back to health. The vendor used this type of board on one nail and it grew 3 times faster and stronger than every other nail. The fourth side (grey) is ideal for finishing when you don't have time for a polish. I also use the white side (buffer) for over polish to create a subtle matte look. The pink side can be used directly on the nail to buff out ridges.
