If you have 1 pack, you can use one sort of socket (6.35 mm, 9.5 mm, 12.7 mm), so it will be saved. Matt nickel plating (matte plating) was not so familiar with it, so I had a little discomfort, but the processing precision was not rough and it was of sufficient quality. It is good to be usable also for impact drivers.
