1, look at the packaging. Genuine Nestle Crunchy Sharks packaging is very clear, both pictures and handwriting are not any blurred places. But the fake Nestle Crunchy Sharks will appear blurred.
2, look at the color. Genuine Nestle Crunchy Sharks' outer chocolate color is thicker. If you open the package and find that the color of the chocolate is very light, then you need to be vigilant.
3, flavor. Usually, the genuine Nestle Crisp Sharks is a chocolate flavor and milk flavor, very natural. If you open the package and smell the pungent flavor, then you need to be careful.
