There is no exact picture of what is being sold, but I believe those are the regular Darton Iron Ductile Sleeves. They are possibly not Cut to spec and would need additional machining by a qualified machinist who knows the specs of cutting the flats and heights on these sleeves.
My suggestion is to go with the Darton MID sleeves, those are already pre-cut with instructions for your machinist to install. If the place has not done sleeving before, you dont want them to start cutting out the Blank sleeves from scratch and not have the right measurements and tolerances.
