Example Input: THis product (which i am not allowed to return) has ingrediants of salt, spices, hydrolysed soy protein, that last item is the common industry con for adding msg to your food. Every soup on your grocers shelf contains msg, but, i digress. So, the third ingrediant is a form of MSG, further down the ingrediant list is proudly displayed ... Monosodium Gludamate, ...MSG. This does not add spice to your food, it stimulats your tongue into feeling that the food tastes good, when IT DOES NOT. MSG can make dogfood taste like hamburger. anyone who thinks this is making their food taste cajun may be serving ALPO.  Tones and Durkee (sp) do not contain MSG, I prefer Tones!  I have 8 eight ounce cans of this stuff.. would anybody like to buy some hamburger from me?
Example Output: 1

Example Input: Besides the obvious convenience and portability of the individual creamers, I liked this item specifically because of packaging. I couldn't believe how many reviews I read about coffee creamer cups; but many of the Amazon creamer options (both Coffeemate and International Delight) had multiple negative reviews due to the shipment arriving with broken cups thanks to sloppy packaging.  That was not an issue here. The shipment arrived in four dispensing boxes of 50 each (as shown in the photo); those boxes were tightly packed in a thick cardboard box which could take a good beating before damaging the inner boxes. Thus, none of my cups were broken, no waste and no sloppy drippy mess. Plus the four boxes means I could put one in the kitchen, one in the bathroom (we moved our mini Keurig there when we upgraded the kitchen Keurig - best idea my husband ever had), and one at work, with a reserve for whichever runs out first.  If you are looking for these mini creamers but deterred like I was by the negative packaging reviews on other options, this is your best bet. As a bonus, the auto delivery price is very reasonable.
