Product Lineup
Chiikawa Cookie Sandwich Banana Milk Flavor
A banana milk-flavored chocolate is sandwiched, almost overflowing, between crisply baked, thin langue de chat cookies. The gentle sweetness of the banana matches perfectly with the mellow milk. With its light and crispy texture, it's a cookie sandwich that makes you want to eat just one more.
The cookies feature cute square shapes with 'Chiikawa,' 'Hachiware,' and 'Usagi' wearing Tokyo Banana headgear! There are six different expressive designs, such as munching and licking. Seeing the Chiikawa characters might just make you hungry too!
The 18-piece box comes with an original sticker! One random sticker featuring a very satisfied Chiikawa, Hachiware, or Usagi with cookie crumbs around their mouth is included. Enjoy the adorable design that looks like it jumped right out of the package.
