Maybe they're an overstock item from Samsung from the Special Edition release? Maybe wishful thinking, lol? Their site also doesn't show multiple views of the pen, so no way to know the top of the clicker's color.
I'm willing to take a $32 gamble tho, that's how much the yellow irritates me. If it ever actually arrives, I'll let you know. If it really is grey, maybe dark blue Sharpie to the tip?
