This was one of our first Japanese products and one of our most popular. Neruneruneru (means knead knead knead!) is a 3 stage diy candy kit. You make the candy base with water, then add in the fluffing powder which makes it fluff up to something resembling Marshmallow Fluff then dip into the supplied candy pieces and eat. See the cute demo video below for how to do it, the back of the packet has detailed picture instructions.
