Starbucks lids are also known as “coffee cUPS”. The lids are made of a hard plastic and are designed to fit on top of a Starbucks coffee cup. The lids are usually green, but sometimes other colors are available. The lids are attached to the coffee cup by a magnet and can be easily removed.
The lids help to protect the coffee from being spilled and make it easier to drink. The lids are also a convenience for customers who want to avoid having to clean their coffee cup after drinking it.
