I would like to recommend paper cups from mcdonaldpaper https://mcdonaldpaper.com/4-oz-printed-espresso-hot-paper-cups-1000-cs/ — I buy them for my coffee shop, and my customers are happy. The cups are convenient, sturdy, don't tear, and keep drinks warm. Plus, there is a wide range of sizes to choose from — you can find the right size for espresso and large cappuccinos.
