God provides! This was just what I was looking for, as the kids needed some plastic cups for when we are out and about (we have some nicer stainless steel sippy cups we use at home, but I hate to lose them when we're out in public). They've been using some plastic cups they received as gifts for Christmas, but the cups are starting to fall apart and Christmas-themed cups in summer does seem a little out of place. :)
