I actually bought and tried "Sunshine Aquarium Kameda Kaki no Tane Assortment" sold at Sunshine Aquarium. The purchase price is 702 yen (tax included).
Sunshine Aquarium Kameda Kaki no Tane Assortment
"Sunshine Aquarium Kameda Kaki no Tane Assortment" is an original Kaki no Tane Assortment from Ikebukuro's "Sunshine Aquarium". Each bag contains 21 individually wrapped mayonnaise flavors, scallop butter flavors, and yuzu katsu flavors. Each taste comes in a package with cute creatures drawn on it.
Sunshine Aquarium Kameda Kaki no Tane Assortment
Ikayaki mayo
"Ikayaki Mayo" in a pink package is characterized by its fragrant flavor. Mayo has a weak presence and has a slight aftertaste. A junk taste that will leave you behind.
Scallop butter
"Scallop butter" in a yellow package is seasoned with the scent of butter. The slightly spreading taste of scallops and the richness of butter match! It is a flavor that will be appreciated by children.
Yuzu bonito
"Yuzu bonito" in a blue package is a slightly mature seasoning with a strong citrus flavor. The flavor of bonito will come later.
A cute package "Sunshine Aquarium Kameda Kaki no Tane Assortment". All of them are seasoned for adults, so if you are a child, you may like or dislike them. It seems to be a good souvenir for those who like alcohol and elderly people.
