You mean, like the rain?That's a terrible idea.
Ferro rods notoriously corrode in damp conditions,
More enclosed moist conditions. I don't use the things myself (i'm either being historical so it's proper flint and steel, or i just want fire so have a lighter) but the ones i've had kicking about in plastic tackle boxes, rucksack pockets, cooksets, etc have all corroded. Mostly just blooms, but one actually disintergratedYou mean, like the rain?
Out of interest, which ones do you use Woody Girl?Plenty of realy good ferro rods available from the UK at cheaper prices that are better.
This, to my mind is a big price for a bit of extra packaging that costs next to nothing. It looks gimmicky to me.
I have 3 great ferro rods. Non cost me much more than £10, and I use them with absolutely no problems, or need of an aluminium tube to keep them safe and useable. Waste of money to me, plenty of British companies make excellent one's. Why not buy British? Instead of wasting your money.
