I agree with the other review, these chips are not for a sore mouth or tender gums. The chips are very hard and the taste is delightful if you enjoy the salt/vinegar combo. Unfortunately, every bag I received in that case was over cooked! They were very dark and only a few golden brown chips in each bag. They definitely need to improve that!

I used these lollipops for a candy princess costume for my daughter. They came in perfect condition and exactly like the picture shows. They do come in a group of 16...such a great value! I was extremely satisfied!

Ex Input:
Caribbean Joy coconut milk offers a tempting price, lower than its competitors.  There's a good reason for its low price: by all accounts it tastes like half the visible amount is coconut milk, the rest being water. Neither good for pina coladas or cooking, this is a poor value and I can't recommend it to anyone.
