I'm not sure what is supposed to sparkling about these strawberries. The front of the box suggests something carbonated - I guessed champagne. And it did have some fizzy powder in the creme, similar to the Ramune Kit Kat, but it didn't really sparkle in the way I had hoped. No edible glitter or champagne flavored creme.
The Sparkling Strawberry Kit Kat is 99 calories a bar and comes in a box of two. It was white chocolate and pink colored. It definitely smelled like strawberries but it was the fake kind. The taste was also of the fake strawberry variety. The chocolate was a very tart strawberry flavor. It reminded me more of the strawberries I eat back home in America, that need a little sugar sprinkled on them, rather than the really sweet strawberries I get here in Japan. I prefer the sweeter variety so this extra sourness was not something I really enjoyed. The addition of the fizzy powder didn't do much in the way of making it fizzy but may have contributed to the sourness because I remember liking the Strawberry Kit Kat I tried back in May.
Overall, I give this one a lower score. It was too sour and there are several other strawberry Kit Kats out there that I like better. Now maybe if it had really sparkled...
Final Score: 4
