Kai Salon Select Premium Guards?

Has anyone tried these AC blades or know more about them?



There also appears to be a smooth guard that looks similar to the Protouch MG

Are those actual Kai blades, versus a knockoff? I’ve seen a couple blades now that have used the exact same packaging or verbiage as Kai but aren’t.

Pictures are from Kai themselves. I’ve only found them for sale in bulk and shipping from Japan.

If somebody in North America places a bulk order, would be willing to but a cartridge of each. DM on DFS please
