A: Each brick when frozen weighs ~450g (just slightly less than a pound).

**Q: is this product  good/safe for keeping my food cool in a lunch box?**
A: Yes, they are really better than the gel ones, I specifically bought these because of the foam as I has some before and the worked really well.  I would probably use 2 or more depending on the size of your lunch box.

**Q: When not used, should I keep them in the refrigerator?**
A: I don't, I just keep them in the empty cooler, make sure you put in the freezer a good 48 hours before you plan to use them.

**Q: Why is the two pack more expensive than buying two one packs?**
A: I don't know; ask Amazon. That seems true with many of their offerings.
