Indeed and if no propriety tubes are available, although little rather useful vaseline tins are , melt it and pour it into plastic straws and seal by melting the ends. Even melt it and pour it into a larger tin like a boot polish tin or other.How about multi use stuff ? stuff that gets used and kept fresh because it's useful.
A wee tube of vaseline is not only good to stop chapped lips, heal hacks on fingers, good on grazes, etc., but squirted on a bit of stick it'll start a fire with a match, at least as well as any firelighter. It'll also burn with a candle like flame if something wick like is inserted into a (one of those wee metal nightlight holders works to contain the vaseline) glob of it.
