For milestone celebrations, 30th birthday cups in styrofoam keep drinks insulated while adding a custom touch to the table. These personalized birthday cups can be printed with dozens of designs, colors, fonts, and borders, making them practical birthday party supplies for showers, bars, or gathering spaces. Use them as birthday cup favors or disposable drinkware for beer, water, soft drinks, tea, or other hot and cold cups. Made and printed in the USA, the cups are recyclable #6 polystyrene and CFC- and BPA-free, with lids available for most sizes except 4 oz for convenient serving at parties and events too.
