First time buyer of KA-ME Rice Crackers and I'm very impressed. These are very light, crisp and flavorful. They are as good plain as they are with cold cuts, fruit, etc. Unfortunately, the ones I purchased may be the last I get from this source. Right after I purchased the dozen packs, the price per dozen increased 44% to its present $37.99. Fortunately, I have enough to last a while, but assuming the price stays the same, these are my last KA-ME.
Polarity: Negative
Output:
False
