POLO Lighter Refill Butane:

POLO Lighter Refill Butane is an extra purified gas with near zero impurities, making it ideal for use with jet flame and turbo-flame lighters, as well as refilling butane lighters and other butane-powered products.

To fill: Hold the can firmly near the top, invert it, and press the nozzle into the lighter’s filling recess.

This should make it clear and concise for your needs. If you need any further adjustments or additional information, feel free to let me know! 😊
