• Size: A4 (approx. 310 × 220 mm)

• Material: PP (polypropylene), single-pocket style

• Printing: full-color front art with logo; semi-opaque white backing so paperwork inside doesn’t show through too much.

Another piece from the Balloon Flight collaboration!

These are standard Japanese “clear files” (A4クリアファイル) – thin polypropylene folders used for storing documents, tickets, prints, etc. Each file features artwork of a Pizza Cats member drifting with a bouquet of balloons themed after their unique personalities and items from the show (pizza slice, lanterns, shuriken, etc). The character’s name is printed in big retro text across the front.

What’s in the set here:

• Yattaro (白) – blue frame with lots of series balloons and the classic “PIZZA CATS” red round balloon.

• Pururun (赤) – pink frame, big heart and make-up-themed balloons; super cheerful art.

• Sukashii (青) – indigo frame with bolts, star, and rose balloons; Sukashii hangs on a ribbon like a swing.

• Great for storing art prints, stickers, artwork or ticket stubs.

• If you plan to display them, slip each inside an A4 acid-free sleeve to avoid UV fade and scratching.

• They fit perfectly in standard A4 clear-file binders if you want to keep the whole collab together.

Before I was neck-deep in model kits and acrylics, this adorable Kyattou Ninden Teyandee stationery set was one of my first collector’s items! 💌

Printed in a soft red halftone style, it features Otama and the Nyanki crew in an early-2000s doujin aesthetic — complete with lined writing sections and those charming retro page borders.

There’s something so nostalgic about fan-made stationery like this — playful, handmade, and full of love for the series that started it all. 💖

• The credit “Anzu 1995” appears on the bottom of the yellow/orange sheet. That suggests the artist (or circle name) is “Anzu,” and “1995” might be a date mark — perhaps the year the print design was made or copyrighted (or a stylistic signature).

• The red printing style (duotone + halftone shading) and layout (lined writing space + character border) are typical of mid-90s doujin / fan stationery.

• The drawing style — expressive eyes, simplified tones, and decorative patterned backgrounds — aligns well with 1990s anime merchandise tie-ins or doujin print goods aesthetics.
