It's also nice if you frequent Starbucks a lot and don't want to spring $10 or so on one of their other cups, as it's good for a 10 cents bring-your-own-cup discount.
The cups is made of recyclable polypropylene, can be used for Tall or Grande drinks, and comes with a matching plastic lid.
The holiday design on the cup is not all that Christmas-y though. I think the design is supposed to be a snowflake, but it could also be a starburst or something.
The Starbucks Holiday Reusable Cup is available for a limited time at participating US and Canada Starbucks stores.
