The files themselves are great, work well and with some sensitivity and with great precision. The criticism, and also the reason for the missing 5th star, is the lack of quality. The packaging was very oily when arriving from the inside, the plastic handles smelled very artificial and are not really of a high quality of workmanship. Nevertheless, the price is unbeatable well and in practical terms to make the files do a good job.
Conclusion: in three words? cheap, oily but practically speaking good .. even if it's more than 3 words.
