shipping packs?

Are shipping packs the same as those hand warmer heat packs?

I ordered 10 - forty hour heat packs and I though that would be enough. However I couldn't find a cooler that was big enough to hold 22 coffee cups (with bettas) - well I found them but they were like $150 - so I got 2 smaller styrofoam ones. That's 5 per cooler for this trip and now I am not sure I have enough. I am leaving today or tomorrow so I can't order more.
If anything goes wrong on this trip - my bettas will freeze.


Can I use handwarmers in place of the uniheat packs if I run out? My former work has then 24 hours ones.

Hand warmers are same concept, just shorter duration is all. But yeah, load up on hand warmers. Good luck with your trip!

Seems to me like it would do the trick. Best of luck on your trip. You're brave!
