Gillette Wilkinson Sword blades: what's the deal?

Hi everyone! I was searching for new blades to test out, and I came across these ones, but I am perplexed.

Aren't Gillette and Wilkinson 2 different, competitor, companies? What is this blade, a joint venture? I'm, lost here. Also, did anyone try them? Aren't those any good?

Thank you very much!
