These party cups are super easy to use. Just take them out of the cello wrapping and fill them with your favorite drinks like soda, juice, or even some cocktails for the adults. They're great for golf - themed parties, tournaments, or any gathering. When it comes to cleaning, you can hand - wash them with mild dish soap and warm water. Avoid using abrasive sponges as they might scratch the plastic. Store them in a dry place, away from direct sunlight to keep them in good condition. Also, don't try to put them in the microwave or dishwasher as the high heat could damage the cups.
