These clear acrylic glass holders are easy to use. First, make sure you remove the protective film before attaching them to your acrylic champagne stand. They're designed to fit only our acrylic stands, so ensure you have the right one. You can use them for double - side displaying, which means you can show off more glasses. They're great for events like weddings and parties. To keep them in good condition, just clean them with a soft, damp cloth. Avoid using abrasive materials as they might scratch the acrylic. Also, since the glasses and stands are not included, you'll need to provide those on your own.
