What Am I

[SolarLune]

I just thought up this game on the spot in a few seconds. Someone will give a description of an object, and others must guess what the object they are describing is. The guesser who gets it right gets the next turn (the question-asking person will confirm the answer); if that person doesn't pose a new question soon enough, or the question-asking person doesn't reply with the confirmation of the answer, then anyone gets the next turn. So, I'll start off.

I stand, translucent and eternal with my inverted partner; both of us decked with silver bowlers. What am I?
