A bit dry but still good. They may be perfectly all right; I just thought the noodles were hard and dry. I'm still enjoying them.

My son and daughter-in-law told me about these chips and they purchased a few bags at a store and I will say they are higher in stores then you can get them online on Amazon. They brought me a bag and I was hooked! So I ordered popchips online and they are the "BEST" chips!! There wasn't a flavor I didn't like or that my family didn't like. I am a (chipaholic) and these are better for you and a great tasting chip. I highly recommend these to anyone that can't do without eating chips either with a sandwich, hamburger, or just to munch on midday. You won't be dissapointed.

Brew it correctly and you really get a beautiful cup of tea.  I highly recommend this brand.  It is by far the best bagged green tea I have found, and I have tried about all of them.  I brew one bag in a 12 oz mug for 2 minutes.  Absolutely perfect.
