I have a tall go-cup for when I take a soda with me in the car. I like to use a straw in the hole on the top. The last package of straws that I bought did not even go to the top of the cup! They have shrunk the straws by an inch or so from the last box that I bought. So, I had to measure my cup and now I take a teeny tape measure with me when I go to the store just so that I can get a box of straws that are long enough.
