To use this vintage beer bottle, you can either use it as a display item to add a touch of the 1960s charm to your room or, if you wish, you can fill it with some decorative items like small flowers or sand. When handling it, be gentle as it's an old item and the glass might be more fragile. For maintenance, clean it with a soft, damp cloth. Avoid using harsh chemicals as they could damage the woven plastic covering. Store it in a cool, dry place away from direct sunlight to prevent any fading or damage to the materials.
