Designed to perfectly fit with any regular Zippo lighter case, Zippo's Arc Lighter Insert grants smokers the ability to further customise their lighter. Forgoing both butane and Zippo's own lighter fluid in favour of two powerful plasma beams, the double beam insert offers a windproof flame source that can easily be recharged while retaining Zippo's beloved click sound. Durable and built to last, this insert continues Zippo's reliable reputation.
