Believe it or not, that is how it is spelled right on the product! 
I'm talking about the Asahi Pentax Helicoid Extension Tube. I found one today and it is genuine Pentax, not a third party.
It's rather comical because Japanese often mix up L and R when speaking and writing English. Someone must have caught this error before it was exported to the U.S. At least I hope they did!

The interesting point here is that Pentax initially seems to have produced a product with a glaring typo but then corrected it somewhere along the line.
