The products are amazing, but with this order, the blue cup lid does not work properly or it could be the cup is not made correctly. I hand washed it so it couldn’t be the dishwasher and it’s not like the other cups, as I have no trouble with them. It’s just the blue one I have trouble with. I’m not sure if it’s the cup that’s messed up or the lid that’s messed up, but one of them is definitely.
