Shimmer Logo 20oz Tumbler

It’s FDA approved plastic meaning like there are some plastics out there people are scared cause cancers and stuff but pp is one of the safest

And you don’t microwave the cups

If they want to use it for coffee they can make it and pour it in there or make the coffe directly into the cup from a coffee pot

I would also advise hand wash only not hot water

I hand wash all of my tumblers with Luke warm water😊
