I use HOGG brand double wall, insulated stainless steel tumblers with lids. They will keep beverages hot or cold for a long time. Each tumbler is handmade and unique, not made in a machine. They are finished with several layers of FDA compliant epoxy which gives you a glass like finish. No two tumblers will be exactly alike.

Care instructions-Hand wash with warm soap water. Do not microwave or put in the freezer. Do not drop.
