NGK spark plug caps "Designed to keeps water out"

[deltarider]

Yes, it's about this 'keeps'. Bought four NGK sparkplug caps today and this is what it says somewhere on the packages: "Designed to keeps water out". Is this 'keeps' a genuine NGK typo or did I buy counterfeit caps? Anybody who can check?

I've heard of counterfeit plugs but never the caps.
Bought some recently on ebay and they were pretty cheap, but work and measured ok, but threw the box away.
Interestingly didn't realise there are so many similar looking but different caps. ie an VD05F (8032) and a VD05F (8052) (which I bought)
