What are thse cups made of? I'm looking for something that will not break.
This mug is made of SAN (Styrene Acrylonitrile). Which is a very strong material and safe for dishwashers.
Hi..Are these stackable mugs microwave safe ?..Please advise. Thanks
These stackable mugs are made of SAN melamine, and is recommended that they not be heated in microwaves. Thanks
