Great lid!

I can turn my 16oz Tervis Tumblers into sippys!  It bothered me that her drinks tasted like plastic if they were in any of her plastic cups for more than an hour.  These BPA free silicone lids fit cups with a 2"-3.75" top.  I put her watered down orange juice in the fridge last night and it tastes good today 👍  I did have one wet on a wavy cup with a 3" rim that popped off when she threw it off the table...but these Tervis cups have held onto them for a few spike on the floor episodes.
