A Clipper lighter is a small, refillable butane lighter known for its cylindrical shape and replaceable flint system. It was originally designed in the 1970s and has become popular worldwide for everyday use and among smokers because of a few distinctive features:

• Refillable fuel tank – Instead of throwing it away when empty, you can refill it with butane gas.
• Replaceable flint – The flint wheel assembly can be removed and replaced, extending the lighter's lifespan.
• Round body design – Unlike many disposable lighters with rectangular bodies, Clipper lighters have a smooth cylindrical shape that fits comfortably in the hand.
• Removable flint tube – The removable striker assembly can also be used as a packing tool for rolled cigarettes.
• Pressure-adjusting flame – Tilting the lighter sideways can slightly increase the flame size because of the way the fuel is delivered.
• Collectible designs – Clipper releases thousands of different prints, colours, and limited editions, making them popular collectibles.

A typical Clipper lighter is about the same height as many disposable lighters but slightly wider and heavier due to its refillable construction. It is generally marketed as a more reusable and environmentally friendly alternative to fully disposable lighters.
