Sour faces.
Bit expensive but great fun, lots of sour faces when eating them. Packing needs to be stronger as two sides of the bay split.

extremely sour but not to the point of stripping the skin off your tongue
My daughter loved the sweets, the only reason i didnt put 5 stars was because it would be nice to get more for your money. They are extremely sour but not to the point of stripping the skin off your tongue 🤣😁🥰

Problem with packaging but good amount of sour for beginners.
I LOVE sour candy and literally anything sour if i can get it when i see it. After tasting a good one after the packaging ruined quite a few of them they are about a 6.5/10 scale but if you are not used to sour about 9/10. The only reason im not giving this product 5 stars is because of its poor packaging as when it arrived it was broken open from shipping it to my adress and all of them were at the bottom of the amazon package and this got rid of a lot of the powder which makes it sour. I might of been one of the unlucky ones but this is still an issue that it can even happen.

Would recommend if you like sour sweets
This sweet delivers a bold sour kick right from the start, and impressively, the tang lingers throughout. Unlike most sweets that lose their edge after the first taste, this one keeps the sour alive—just dialed down to a gentler zing that lasts.

Split bag
Bag arrived with a hole in the side, not happy as these are a sticking filler present
