lighters

yes. Clipper lighters refill with standard butane, and the flint is replaceable too. keep it topped up and one lighter will last you years rather than heading for the bin. that's what makes them cheaper over time than disposables. refilling takes less than a minute once you've done it once.

turn it upside down, press butane into the valve at the base in short bursts, wait a minute for it to settle, then spark.

the pop-out flint holder on a Clipper doubles as a poker. slide it out and it's handy for packing a bowl or clearing a blockage without reaching for anything else. it tucks back into the base when you're done. a small thing, but it's part of why people stick with Clippers.

refillable works out cheaper and wastes less. disposables are fine as a backup or when you'll only need it once.

yes, singles up to trays and multipacks. cheaper per unit and you're never caught short.
