These are very good quality. For some reason the sizes are not listed so it includes in 3/8" drive sockets t30 t40 t45 t50 t55 and in 1/4" drive t8 t10 t15 t20 t25 t27. Needed em to get the intake manifold off my truck worked as expected. Also the case they come in has reclosable tabs to organize/hold the bits.
