Will a straw fit thru the top opening? What is the diameter of the top sip opening

Will the 14oz double wall Tupkee tumbler be returning to stock ?

This item was a COMPLETE waste of $$$$$!!!!!

If the lid is made of glass, is it possible that after 2 weeks of use the mouth of the lid changed the shape from smooth to wavy? I used hot coffee as

No, for glass to change it’s shape, it would have to be heated to a temperature many times hotter than the hottest coffee.
