I love it. There are two types - fruity and milky. I like the fruit ones, which are served cold. It is basically a glass of fruit juice with ‘bubbles’ of a different flavour (the bubbles are similar to small bath pearls -remember those? - made of juice). You drink the two flavours together through a wide straw. I like cherry juice with apple bubbles.
My granddaughters have been drinking it for at least 5-6 years. Mind you they do live in London. It hasn’t got to SW Wales yet. They always ask around when they visit here
