Jen,
Yes, got the hint, you want to know more
So just for you I've done the leg work.
Great for our purpose, as there is no heat capacity loss until you activate them. I strongly recommend buying two sets.
Here's the product data on the Trafalgar ones I bought at Aldi.
Trafalgar Code 101316 (pocket warmers 2 per pack) and
Code 101317 (4 per pack - what we would call EP warmers if you have a
good EP case).
Trafalgar Aust. contacted, about these items, said they were a special lot purchase exclusive to Aldi. Not available elsewhere.
Aldi, also confirmed the above, said may be another special buy next winter season - non-committal. As these were on special sale with the winter snow gear specials, may give you a clue when to expect them again
I previously purchased my first lot from Ron at Sirius Optics Brisbane. Brand is Shin Bio (made in Aust.) Below is their direct order / price list:

I have one Large Heat Pack 260x180 (great for back ache)
also two Small Heat Packs 125x90 (pocket hand warmers).
Aldi ones were less than half the price of the Shin Bio on-line prices.
Unfortunately I spotted the Aldi ones too late and only found two of each left
All mine are all safely stowed - very attractive items
BTW just checked with Ron at Siruis Optics, because he is a thoughtful man, he will have some Shin Bio ones at Astrofest - his price very competitive. No affiliation yada yada.
Cheers,
David
