jack,
i have purchased this in the past: they are oval clear tubes with a filling tray from sks bottle and packaging, and i am about to fill 500 tubes in the near future. no other company i am aware of gives me the tubes and filling tray. you can buy separately, but it was a help to get started and a good price, also you can get the round tubes with the tray as well:
SKS BOTTLE & PACKAGING CLEAR OVAL TUBES WITH TRAYSKS BOTTLE & PACKAGING ROUND TUBES WITH TRAYoops, now i see they are only giving you half the amount of tubes the tray fills (24).......tubes aren't that expensive it's the mix of your lip balm!
also, most folks i found do not like the tins (very few), i tried a few, so my HO is stick to tubes. this may be different for you.
i stick to one recipe jack for the most part, a copy of the famous one (peppermint flavor) you can get wound up in trying all sorts of things, it makes your head spin and your hard earned cash disappear paying for all the ingredients. for kids keep it simple, they like all the 'funny' flavors and are easy to please.
for adults maybe a couple flavors?
candles? you will probably do well on the candles jack, folks love candles!
