Zarfs are the protective cardboard sleeves for disposable coffee cups, also known as Java Jackets, coffee clutches, and cup holders. They were originally decorative metal stands for handleless cups.
The protective cardboard sleeves that surround disposable coffee cups are technically called zarfs. The Zarfs are known by many other names, including Java Jackets, coffee clutches, coffee sleeves and cup holders. Incidentally, before cardboard sleeves became known as a zarf, a zarf was a decorative metal stand for a cup of coffee or tea that didn’t have a handle.

When coffee first became popular in the 13th century, it was served in tiny, handleless cups, which were then placed in a decorative zarf to prevent the drinker’s fingers from burning. Some ancient zarfs were quite intricately carved and were often made from precious metals, rare woods, or even ivory.
Making zarf can be big business: The United States alone consumes more than 16 billion cups of take-out coffee a year, and most of them come in cardboard sleeves.
In Arabic, the word zarf means “container” or “envelope”.
