      What cup size will a Runsip® Flex lid work on?

      A Runsip® Flex lid will work on most cups that hold between 8 and 20 fluid ounces.  More precisely, it works best on cups with an internal diameter of between 2 3/4 inches to 3 1/2 inches.  However, with practice it can be attached to cups larger and smaller than this suggested range.

      It is always best to use cups that have a snug fit into one of the rings or steps on the underside of the lid.  Runsip® Flex can be attached to cups that are too big to fit into the largest ring or step but the seal may not be as good.
