What is the OTONA RANDSEL?

Inspired by our best-selling bag, the Randoseru, the OTONA RANDSEL takes all the best qualities of the classic Randoseru: structured body, weight distribution technology, and large capacity, but offers an updated and sleek silhouette built for today’s world.

The Meticulous Craftsmanship

"OTONA RANDSEL" may seem simpler than Randoseru, but it boasts over 150 components and involves a meticulous manufacturing process with more than 300 steps. This focus on durability ensures it retains its shape for an extended period. To avoid an overly rugged appearance, the design is carefully tuned to strike a balance that reflects the mature dignity of adults while maintaining its strength.

Customer's voice

Dear Tsuchiya Kaban Team

Yesterday I have received my first product from you, the Otona Randsel 003large.

I have to say, I am blown away. What a fantastic product and craftmanship (including the packaging). I am 51 but was jumping around like a kid in a candy store. This bag will be a loyal companion and certainly not the last product I buy from you.

Congratulations to the entire team for creating such a product and upholding the traditions of outstanding craftmanship – I bow to you.

Mr. Sertel
