Marukawa Which One Is Suppai Sour Soda? Gum Pack

I got this in a Snack Rescue Box and ate all of them at once.

The sour one tastes really good

Great flavor, I preferred the sour stick so it's a shame it was only 1 of the 4. That being said, the sour was actually decently sour for a Japanese candy. I find a lot of the "sour" stuff isn't all that sour. The flavor went away quickly but the texture was nice.
