This idea came about because I saw that most Indonesians throw away eggshells and most Indonesians don't understand that eggshells have a very high level of calcium because for Indonesians eating eggshells is a strange thing but in fact eggshells can be used properly as a food. high in calcium. When you eat this snack in a box, you will feel the taste of a new chocolate variant with fermented bananas. This snack which is rich in calcium and probiotics will be packaged in a cardboard box because it is easy to use, easy to recycle and cheap. Each container contains 100 grams. Later, snacks rich in calcium and probiotics can be found in supermarkets or can be ordered directly through our website and social media.} }
