Using this cup holder is easy. Just place your milk tea cup in the holder. The detachable chain allows you to carry it around conveniently, like hanging it on your hand or bag. When it comes to cleaning, use a soft, damp cloth to wipe it gently. Don't soak it in water as it may damage the PU leather. Store it in a dry place when not in use to keep it in good condition. Also, avoid sharp objects that could scratch the surface of the holder.
