Using this plastic glass cup is easy. Just open the cover, fill it with your favorite drink, and you're ready to go. It's great for taking on outdoor trips. When using it, be careful not to drop it on hard surfaces as it's made of plastic and may crack. To clean the cup, simply use warm soapy water and a soft sponge. Rinse it thoroughly and let it dry before using it again. If you've customized the logo on the cup, avoid using abrasive cleaners that could damage the print.
