minä perhonen creates timeless, all-original garment textiles that are specially dyed, embroidered, and woven to recreate hand-drawn designs.
We created a techo cover using two textiles: “jellybeans,” which once appeared in the Hobonichi Techo lineup, and “tambourine,” which has been popular among many. The playful design features two shapes of “circles” that happily overlap: the fluffy, sweet-looking watercolor drops and embroidered dotted circles.
The material is linen and pleasant to the touch. The “tambourine” embroidery adds a fun touch.
The butterfly-stopper pen holders and cover interior are a refreshing light blue. Two dotted lace bookmarks are attached.
Each cover contains a unique arrangement of the pattern. We hope you enjoy your one-of-a-kind cover.
Also available is a small tote bag made with the same textile.
In the Hobonichi Techo 2025 lineup, the Original book comes in either English or Japanese.
*The English book is only available as the January-start version.
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.

In order to provide you with the most satisfaction for your product, we've compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Please be sure to read this information carefully before placing your order.
Each item is individually assembled and sewn by hand by a factory worker. Best efforts are made to ensure consistent sizes and specifications, but there may be slight differences.
Please note that embroidered areas may contain threads that protrude from the design.
Due to the varied thickness of the material, embroidered designs may appear slightly bent.
The dye in the cover may stain other objects if it rubs against or sticks to them, especially if the cover is wet from water or sweat from your hands. Please store with care.
Due to the structure of the cover that opens flat 180 degrees, exterior stitching areas may appear puckered and lining material may be loose.
The pen holders are rigid at first, making it difficult to insert pens. You can speed up the breaking-in process by rolling the pen holders in your hand.
The pen holder is designed to perfectly fit the 12.2 mm (0.48”) diameter Jetstream pen offered as a free Hobonichi Store Exclusive. 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.
This cover uses thicker materials than usual, so it may not fit. Forcing it into a Cover on Cover may damage the products.
Please avoid storing your product in hot, humid places or placing it atop other objects for long periods of time as this may result in lower quality and color stains.
These Hobonichi Techo cover designs were directed by minä perhonen, but produced by Hobonichi. Inquiries about these covers cannot be answered at minä perhonen shop locations, so please contact the Hobonichi Store with any questions or concerns.
If you’ve used any of these products, we welcome your notes on what you like about them or what led you to buy them so we can share it with customers who are currently considering these products. We’d also love to welcome comments from customers who purchased their techo outside the Hobonichi Store or received their book as a gift.
