Star Nail Polar Block 4-Sided Nail Buffer Block, Soft White

This is a good product for buffing your nails. As some of the other reviews noted it does not last long. However, it is a good product while it lasts.

Don't waste your money on any other brand of nail file blocks, POLAR BLOCKS are the only ones that hold up and do what they're supposed to do. We couldn't find these for a while and bought a few other brands that were just awful, this brand is far superior to all others and the blocks allow you to get into tight corners of your nail as well. Great for toe nails and finger nails.

Wear out very quickly. They do the job, but don’t last.

I'm a professional nail technician and I like this brand the best.

These are way too soft and don't hold up very well without crumbling and the sand falling off. The older ones used to stay stiff much longer.

I have used these in the past and like them very much for buffing the ends of my nails that are currently having a tendency to chip. For the price these work very well and I would recommend them.

Good product, but not as good/ long lasting as they used to be. The old one I have from a few years ago ( I bought at a local Sally Beauty Supply) seems of better quality.

My favorite blocks. Always leave my nails smooth and are long lasting.
