Tragen: Mustard A5 Cousin Size - Techo Lineup

TragenMustardA5 Cousin Size

2026 New

This cover is designed to carry your techo along with important tools like pens and stationery. The name “tragen” comes from the German word meaning “to carry.”

Its standout feature is the generously sized pocket, but its overall appearance remains clean and minimal. The vibrant yet subdued mustard color gives it a beautiful finish that suits anyone, regardless of style. Though it folds into thirds and fastens with a magnetic closure, the cover is light in hand. The aim was effortless elegance, something that looks sharp without being flashy. The material is a soft nylon with a sophisticated sheen.

The zippered pocket features a gusset for roomy storage.

The inside of the pocket is lined with black fabric, creating a striking contrast with the mustard exterior.

The cover closes with a hidden magnet, which is padded with a leather patch for a softer touch. The outer pocket also features a leather zipper pull.

Inside, you’ll find ample storage: a leather pocket on the right side and five card pockets on the left. The pen hook is designed to hold your pen by its clip.

On the back is another handy pocket for quick-access items like tickets or small notebooks. A “HANDWRITE” tag adds a playful finishing touch.

Use your favorite tools and enjoy the simple pleasure of writing by hand at any time.

Tragen comes in five different colors. We hope you’ll find the one that speaks to you.

A flat design pouch made from the same material as Tragen has also been added to the lineup. Perfect for carrying your HON-size techo.
