A: This is an odd issue we’ve discovered with the silver pyramids: they arrive with sticky feet. Apparently, something about the process they used to apply that silver coating resulted in there being a bit of residue on the undersides of each piece. Fortunately, the gunk rubs off easily enough. We recommend giving the base of each piece a slight buffing against a piece of cloth (the sleeve of a T-shirt works great) then simply using your finger to ball up and remove the lingering bits of residue. Unfortunately, yes, this is a little annoying, and for that we apologize. (See this backer update, Beware the Sticky Residue, for more about that story.)
