Anyone know if these are rebranded Personna blades? Looks to be from the style of key and amount of blades per key which is 20. Also that is a great price for a 3 pack of injector blades. They are right there for price compared to Connaught with shipping included for 60 Personna injector blades. https://www.amazon.com/dp/B07VQPFK68/?tag=thshde-20
A while back while browsing the web, there was an article about them being Personna blades. And that's a great deal.
