Koikeya Launches Crowdfunded Polinky and Karamucho Character Stickers to Attract Younger Fans

Koikeya Co., Ltd. will begin accepting pre-orders for 'Koikeya Potetto Seal,' 3D stickers featuring characters from its popular brands 'Polinky' and 'Karamucho,' from June 18 to July 13, 2026, exclusively on the Koikeya Online Shop. In a first for the company, the product will only be commercialized if the pre-order target of 2,500 sets is achieved.

Since its launch in 1990, 'Polinky' has been a beloved snack for over 35 years. However, internal research revealed that its appeal was not effectively reaching younger generations. In response, this project was initiated as part of a strategy to redefine the brand's value and encourage younger consumers to get to know and love 'Polinky'.

The product is a two-sheet set featuring designs of the 'Polinky Theater' from the snack's well-known commercials and the family tree of 'Hee-obaachan' and her 'Hee-ichizoku' clan from the 'Karamucho' brand. Each sheet contains about 30 stickers, creating a collectible item.

**Product Overview:** - Product Name: Koikeya Potetto Seal 2-Sheet Set (Polinky Theater & Hii-ichizoku) - Contents: 2 sheets - Price: 1,240 JPY (tax included) *Separate shipping fee of 220 JPY applies. - Sales Period: June 18 (Thu) - July 13 (Mon), 2026 - Retailer: Koikeya Online Shop - Commercialization Condition: Production confirmed upon reaching 2,500 pre-orders. Orders will be canceled if the target is not met. If successful, products will be delivered in mid-September 2026.

**Related Event Information:** In early July 2026, a sticker exchange event featuring the Polinky character 'Jean' will be held at the sticker exchange cafe 'Sharepuku Harajuku' in Tokyo. The actual 'Koikeya Potetto Seal' stickers will be revealed for the first time at this event. Participation requires advance reservation, with details to be announced on the store's official Instagram.

'Sharepuku' is a popular sticker exchange cafe among Gen Z, operating on the concept of 'sharing cuteness.' Since opening its Harajuku store in December 2025, it has expanded to other locations nationwide.

Additionally, a promotional campaign will run on X (formerly Twitter) to support the product's launch. By following the official Koikeya account (@koikeya_cp), reposting the campaign post, and replying with the designated hashtag, 30 participants will be randomly selected to win a snack assortment. The campaign runs from June 18 to June 24, 2026.
