For Business

With a 12 cm deep main compartment, the randoseru comfortably fits a 13-inch laptop, notebooks, pens, a water bottle, and even a gym outfit. Thanks to its structured build, it retains its shape and stands upright on your office desk.

The materials are treated with a scratch-resistant and water-repellent finish, making the bag easy to care for without special maintenance.

For Travel

Whether you're carrying a camera, passport, or guidebook, the randoseru is an ideal travel companion. Its durability, light weight, and functional structure make it perfect for everyday use during your trip.

Its design also makes it photogenic—especially when captured against Japanese scenery. After your journey, the randoseru continues to serve as a reliable backpack for commuting or weekend outings.

Quality & Easy Care

Each randoseru is made from carefully selected genuine or synthetic leather, ensuring both durability and elegant appearance. The water-repellent and scratch-resistant finish allows it to be used even in the rain with peace of mind.
