Schick Injector and P-20 blades.

Is there a difference?

Think you meant Proline B rather than the P. The B will fit into an Injector, but need to be inserted into a host Injector dispenser, so it can be injected into a Razor. The Type P is is 50mm and can be used in AC Razors.

B-20 is made in Japan
Yellow pack from China

And there are these also from Japan - Schick 1 (2 is a twin blade)

I prefer vintage blades though

As stated above the Proline's do not have the bayonet on the cartridge

I’ve tried all the currently available injector blades (not many). The two Schick brands depicted above are my top two, but I give a slight edge to the yellow pack which, imo, seem sharper and smoother. As @MPF9 indicated, only injector razors with the right style head will accept the B-20s. For me that’s the Asylum Injector.
