Foldable Travel Cup is a portable, collapsible silicone cup. Simply expand by pulling out the tab on the bottom of cup or compress by pressing down from the top. Approximately 16 mm when flattened, it can be easily fitted in a pocket or purse, making it ideal for taking medication and traveling. The pull tab constructed on the bottom of the cup not only provides a sturdy structure but also proves suitably hygienic since fingertips doesn't need to run across the rim or inside of the cup while folding and unfolding. It's a fantastic alternative to disposable cups!
