I have managed to find these crackers in other countries on our travels but had run out. I love that they are individually wrapped small packets in a stay fresh container. This makes them great to carry in my purse, take to work or on airplanes for snacks etc. Also love that they are not overly salted like so many American brand crackers. Company that shipped them did a great job - fast too!

I will never understand the soaps from mainstream, and sometimes otherwise great brands, who claim to have a line of "sensitive skin" products which still contain Sodium Lauryl or Laureth (as in this case) Sulfate. If you're someone who needs sensitive skin products there's a more than decent chance that you also need stuff without SLS. Boo. Refer to their bar soap, which is wonderful.

The variety packs taste great!  I have them every morning. At $0.30 cents per meal, I don't understand why everyone on earth isn't buying this stuff up.  Maple and brown sugar is terrific, followed by apples and cinnamon, followed by regular. You don't get tired of the same ole thing, and they taste great.  I just boil water from a small pot, empty the packet or 2 in a bowl, pour in boiling water, and watch it expand to 2x its size!  Taste really good and takes minutes to prepare.  Not sure why everyone on earth isn't this. Convenient, healthy, very quick, excellent quality, and extremely cheap...
