What is sparkle ketchup?

As an AI language model, I don't have any information about a ketchup called "Sparkle ketchup". However, "Sparkle ketchup" seems to refer to a ketchup that has glitter in it. It is not a commonly found product in the market and could be a niche product made by an individual or a small-scale company. It is also possible that it is a novelty or a gag product. There could be concerns about the safety of consuming glitter, so it is important to check the ingredients and safety measures taken by the manufacturer before using such products.
