Colors: Black x Clear Blue A5 Cousin Size - Techo Lineup

ColorsBlack x Clear BlueA5 Cousin Size

The Colors series is a regular part of our cover lineup, available in a variety of solid colors and featuring the “butterfly-stopper” pen holders to keep your cover shut. We’ve implemented many improvements over the years in response to customer input, making the Colors series one of the most user-friendly options in the lineup.

Black x Clear Blue is a popular and versatile black cover that returns this year with a clear blue interior that gives the cover a breezy, refreshing look.

The high-quality polyester material gives the cover its sturdy feel and subtle shine. Made for ultimate comfort and portability, it’s made to be thin, yet sturdy enough to last a long time.

The “butterfly-stopper” pen holders act as a hinge, keeping the cover safely shut while you store a pen inside.

The cover contains two bookmarks, one with a rectangle charm and one with a triangle charm, so you can keep your place in two parts of the book, such as the monthly calendar and the daily page.

Sold separately is the Cover on Cover. In addition to protecting your cover from wear and tear, the Cover on Cover is a great place to store postcards, pictures, and other decorations to customize your cover at any time.

The Cover on Cover comes in a variety of designs, such as illustrated prints and stripes, so you can combine a wide range of colors and patterns to match your every mood.

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.

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 and print may vary slightly: The cover's color and print pattern are created by dyeing or printing onto white fabric. While we take care to ensure consistency during production, slight variations in color or pattern may occur between individual items. This may also happen across a single cover, such as a pocket compared to the rest of the cover. Minor print blurring or uneven coloring may also be present. In addition, on rare occasions, there may be small black or white dots visible on the print. This is an unavoidable aspect of the manufacturing process.
