it was useful, but the metal rods left marks on the inside of our porcelain and ceramic cups
since wood is soft and does not mark, i drilled dowels to the same diameter as the metal rods. now these rods keep the glasses safe AND does not mark them
all you need is a drill press to drill the holes straight
