meh [SEP] i usually buy the makartt pack of nail buffers they work very well but do not last long i saw this by the same seller and decided to try it is small and portable easy to hold but i do not care for it is performance as a nail buffers the shaping sides of the buffet block work fine but the shine side does not compare to the other buffers there is also a small file shaped buffer also not that great the flat buffet may work the best over all not impressed next time i will stick to the file shaped buffers i was buying previously
