Jim Mart Onigiri Message Card Letter Set – Tuna Mayo

A bite-sized greeting that recreates the authentic tear-away opening of a Japanese convenience store rice ball.

Part of King Jim's food-themed Jim Mart stationery lineup, this novelty letter set turns a quick handwritten note into an interactive konbini experience. The set comes with double-sided onigiri message cards featuring a textured nori seaweed print on one side and realistic rice grains with classic Japanese fillings, like Tuna Mayo or Raw Pollock Roe, on the other. To use it, write your message on the blank reverse side, fold the card in half into a triangle, slide it into the custom clear pouch, and seal the top using the included flavor label sticker. The label includes a "To:" space to address the recipient, who then pulls down the wrapper seam just like opening a real store-bought onigiri to read your note. It is ideal for lunchbox surprises, desk memos, thank-you notes, or tucking into gift bags.
