Vials in extreme heat

[BJJ_blackbelch]

Can these vials take the 100+ degree heat for 3-4 days outside in a mailbox? Just thinking if the rubber will melt after a while.

Its constantly been over 100 where I'm at and i have a pack coming while im out of town.

I’d imagine, international packs go through high temps for quite a while and gear is fine once it lands. If it was peptides, I’d be worried.
