The 6mm and the adapter ARE NOT Craftsman, and are unbranded, but look to be good quality. Handle has marks from use, but does not affect performance.
The set includes 10 sockets (4mm-13mm), 3/8" to 1/4" adapter, 1/4" square socket, 5/16" square socket and driver handle. All the Craftsman sockets are marked USA, and the 6mm socket is marked Taiwan. Thanks for looking! (1D)
