Actually they are NOT sold in Israel, or, at least, not the exact types sold abroad ... I live here, and I tried.
I contacted some time ago the Persona factory, they gave me the details of the local distributor, who gave me the details of a barbershop supplier who stock them and is situated near Haifa (where I live).
They are sold here under an old Israeli brand - Edisson. Bought 200 (about 14 $ for the lot) and tried some - excellent blades in my opinion.
Now they are in drawer - and I'm enjoying a Gem shave ....
