Using these balloons is a breeze! Just inflate them with air or helium. You can use them for parties, decorations, or any special event. When inflating, don't over - stretch the balloon to avoid bursting. Since they are non - returnable and non - refundable, make sure you're satisfied with your purchase. For maintenance, store them in a cool, dry place when not in use. This will help keep the UV - resistant vinyl in good condition and prevent fading or brittleness. Enjoy your balloons!
