perfect because it's Wiha, anyway, the quality is no longer a demonstrate. quality just below the "durabits" with Wiha but for a price divided by 2 and I was not sure that the 28 mm of durabits would be suitable for my magic flip tip Wiha door and those are the Standard are so 25mm. Sending and fast delivery. the bit holder is very magnetic (neodymium magnet) very well and loving the screws ..
