This maybe the best price out there right now with international shipping factored in. The blades are stocked and sold by Amazon.co.jp https://www.amazon.co.jp/-/en/Schick-Injectors-Single-Replacement-Blades/dp/B01MSB24A5/
..oh.....ok....then it makes sense.... .......i just pointed it out because if they were indeed manufactured in the United States, it would be ironic that you would have to pay international shipping rates to get them delivered to the States..
They shouldn't be. There are only 2 major manufacturers of injector style blades that are used outside of the medical industry. Unless Edgewell which owns the Schick brand now is contracting out to Accutec, their branded blades are made in either China or Japan. Accutec on the other hand still makes blades in the US and are responsible for the Personna branded branded injectors and third party brands like Taconic shave. Accutec used to and may still also be responsible for the Supply branded injector blades but they've since changed the amount of blades and grind of the blade to a custom specification so whatever they are stocking is not identical to a Personna blade anymore.
A few months late but I did take the time recently to translate the Japanese text on the Japanese Schick single injector packaging and it says on the actual package that they are made in the United States. I didn't translate the 2-blade injector packaging but I assume... Edit: here is both the single injector blade and the double injector blade packages translated... The text just above the barcode roughly translates Made in America. The single blade is the green packaging. Double blades is the blue packaging.
I believe you are correct but the Twin II blades might be assembled in Japan possibly, Good old Personna blades. (Edgewell) Schick proline P30 blades are made in the USA http://tryablade.com/blade/schick-proline-p-30
They are stocked by Connaught Shaving in the UK. The blades are still not cheap but shipping to the US is reasonable. https://www.connaughtshaving.com/schickii.html
