minä perhonenaaltoA5 Cousin Size
- 2026 New
minä perhonen creates timeless, all-original garment textiles that are specially dyed, embroidered, and woven to recreate hand-drawn designs.
Using plenty of water to mix in with the paint and a flat brush, a collection of arcs that blend together is created for the aalto. This textile was made with transparent watercolor which overlaps in layers, making them look like waves that continue into the distance, and to the far reaches of an endless sea.
The fabric is a linen with a smooth texture. The interior comes in a deep blue shade, while the two bookmarks are yellow and gray, respectively.
The zipper pull is made out of a natural leather, and the butterfly-shaped fastening adds a cute charm.
A cover that promises to refresh you with a fresh breeze and an uplifting feeling every time you open it.
About minä perhonen
minä perhonen is a brand created by designer Akira Minagawa.
First founded in 1995 under the name minä, and renamed “minä perhonen” in 2003. In Finnish, “minä” means “I,” and “perhonen” means “butterfly,” expressing Minagawa’s hopes to create designs as light-hearted and beautiful as a butterfly’s flapping wings.

We’d also love to welcome comments from customers who purchased their techo outside the Hobonichi Store or received their book as a gift.
Please Read Before You Buy
We’ve compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Additionally, the color of the product may be slightly different in actuality than compared to how it appeared on a computer or smartphone screen.
- Inquiries cannot be handled by minä perhonen stores
This cover is produced and sold by Hobonichi Co., Ltd. under the design direction of minä perhonen. Inquiries about these covers cannot be answered at minä perhonen shop locations, so please contact the Hobonichi Store with any questions or concerns.
- Cover may contain variations in stitching or loose lining
Due to the structure of the cover that opens flat 180 degrees, exterior stitching areas may appear puckered and lining material may be loose.
- Pen holder fits pens up to 13.5 mm wide
The pen holder is designed to fit the 12.2 mm (0.48") diameter Jetstream pen offered as a free Hobonichi Store Exclusive Bonus. Pens with certain shapes and materials may be difficult to pull through the holder. The holder can fit pens up to 13.5 mm (0.53") in diameter.
- Color transfer may occur due to friction, pressure, or moisture
Color may transfer to other items through friction or prolonged contact. This risk increases when the cover is exposed to water or sweat, so please take extra care when carrying it near clothing or other belongings.
- Print may have white spots due to texture of material
Due to the naturally-occuring naps (knots and lumps in the material), the print may contain some white spots. This is caused by originally-present naps being printed on, and these naps later coming off the cover. Please understand this is an unavoidable aspect of the all-natural material.
