I bought a bag of Japanese sweets from the Birmingham MCM ComicCon and there were several packets like these. They contain three balls that pack quite a lot of flavour into them. The balls are actually bubble gum but when you first start chewing them they don't have the texture of gum. They are quite strange in that the flavour bursts out of them overpowering your senses until after a couple of minutes of chewing when the bubblegum texture starts to appear. You'd almost be forgiven for swallowing them within the first two minutes, as they don't feel like bubblegum and if you haven't come across them before you wouldn't know.
