I screwed the smallest cap onto my FUG the other week. I like it that way... however, I do want to be able to get inside it to access the bottle of lube I stored there.
Problem is... I can't get the thing off. I try to turn it with a coin, but it's so tightly fit that the coin just slips off and starts stripping the edges of the plastic in the slot... tried some small pliers as well, no dice.
