hey guys!! i recently picked up some vintage camel light promotional lighters from the 90s for my older sibling. however, i have never refilled a lighter nor do i know if its even possible on these ones. i do have some zippo lighter fluid in case it is possible, but i’ll attach a few videos for help because i genuinely do not know how to get them open or refilled. thank you!!
