I've found the bottoms of Bic lighters are no longer made as,they once were,i.e. visibility of contents:Butane!Duct tape around a card is the best solution,IMO.It will be easier to pack,you can get 6ft or better on a card & will be much easier to un-wind.Put rubberbands or innertube(rangerbands)on a Bic,they can be moved to see the contents,provide grip,& make an Xlnt wet/dry tinder,as well as a decent binding to keep the butane pedal locked-up!
