Set of seven screwdrivers in a pouch, nicely constructed (each has a collet so that the blades can be changed) and the quality of the blades is quite good too.
Officially they measure:
0.7mm, 0.8mm, 0.9mm, 1mm, 1.2mm, 1.4mm, 1.4mm.
When I picked out one set at random, my micrometre gave:
0.75mm, 0.77mm, 0.85mm, 1mm 1.26mm, 1.33mm. 1.4mm.
So if you want a range between approx. 0.8mm and 1.5mm, these are fine, but you won't get exact sizes.
See my short description of screw types.for more information.
