LONDON -- Chocolate purists: look away now. Kit Kat has launched a new variety of the classic bar that might just be its strangest yet. 

The Hokkaido melon with mascarpone cheese bar is being sold at airports at Japan, alongside two other flavours currently being tested, including Japanese strawberry, and uji matcha (green tea). 

According to Nestle Japan's website, the new variety sandwiches the "powder of Hokkaido melon and mascarpone cheese between sweet wafers," and is topped off with white chocolate. 

"It features a mild sweetness of Hokkaido melon and a fresh taste of mascarpone cheese," reads the product description. 

This isn't the first quirky Kit Kat variety we've seen, however. In January this year, 24 karat gold Kit Kat bars went on sale in China to celebrate Chinese New Year, and in February sake-flavoured Kit Kats hit Japan. 

But, while some are eager to get their hands on a melon and mascarpone bar, others are less than impressed by the new product.
