Ex Input:
Even with small containers, they don't fill them up.  These little tins are less than half filled and at the price charged it seems a rip-off. Is there some exotic ingredient as costly as gold contained in those tiny squares?  Or how about the cereal ploy, they were filled at the factory but settled in transport. Can manufacturers be honest in their dealings?

Ex Input:
This hot chocolate tastes like hot sugar water with a pinch of coco in it. Although, even the sugary taste is weak, and tainted by the flavor of the artificial sweetener sucralose. The consistency is watery and bland. This is when I made the 8oz cup as directed by the directions on the box.  I do not recommend this product.

I bought this color for a cake replica of the Stanley Cup that I made.  I was using this color for the very first time and I have to say that it was perfect!  I was afraid that the silver would be too dark or matte, but it had a sheen and was exactly what I was hoping for.
