Eco-Friendly & Refillable: They feature a refillable butane valve at the bottom, heavily reducing plastic waste compared to standard throwaway lighters. 

Removable Flint System: The entire spark wheel assembly can be pulled out. This allows you to easily replace worn flints, dry the lighter if it gets wet, or use the housing stem as an improvised poker tool. 

Automatic Flame Increase: When the lighter is tilted upside down, the butane flow increases slightly to create a larger flame, making it perfect for lighting pipes or deep candle wicks without burning your fingers
