Randoseru Leathers

For your chidlren's elemntary school entrance and your daily use, we create with good quality three main materials of randoseru backpacks for customers: cordovan, cowhide leather, and artificial Leather. Each material possesses of corse good its own unique features. However, regardless of the material, our randoseru products are durable with water-repellent and scratch-resistant treatments that eliminate the need for special care for your long use.

*Please note that the case leather used for Liberta does not undergo these specific treatments. As a result, it will naturally change and develop a unique patina over time with use. This characteristic allows you to enjoy the natural aging process of the leather, adding to its charm and uniqueness.

Cordovan Leather

Cordovan leather is often referred to as the "Leather Diamond" due to its exceptional beauty, intricate carving methods, and its rarity. At our company, we source cordovan leather from the renowned tanner, Shinki-Hikaku, located in Himeji, Japan.

Unlike most cordovan products, our cordovan leather is meticulously crafted to retain its natural luster and is treated with a water-repellent and scratch-resistant finish, ensuring its durability and longevity.

We offer a range of 9 vibrant colors for you to choose from: brown, red, lavendor, camel, wine, black, moss green, rose pink, navy blue. Select your favorite color that will accompany you throughout the 6 years of use, reflecting your personal style and preferences.
Also, the price is reasonable. We want more people to enjoy randoseru made of cordovan.

Cowhide Leather

Cowhide Randoserus have three types; Cowhide, YAMAMOTO’s original Denim-like cowhide, and Case leather.
The traditional color of Randoseru is black for boys and red for girls, but today children's individuality is prioritized and a variety of colors are available.

Both Cowhide and Denim-like cowhide leather are treated with a water-repellent and scratch-resistant finish, eliminating the need for special care. These leathers retain their beauty and durability over time.

On the other hand, Case leather is designed to develop a unique patina and change in appearance as it is used, allowing you to enjoy the natural aging process of the leather. This characteristic adds to the charm and individuality of the Case leather.

Artificial Leather

Our artificial leather offers a lightweight and high-quality alternative to genuine leather. Our artificial leather is so high quality that it is indistinguishable from natural cowhide leather. The surface of artificial leather is laminated, resulting in a durable material that is resistant to scratches and showcases a matte texture.
In recent, a new lightweight model was released, 100g lighter than the current artificial leather one.

Other artificial leathers that are different from the main material are used where appropriate, for example interiors and back cushion, aiming for lightness and comfort while taking advantage of the main materials.
To ensure that the finished product is beautifully finished, even small parts and invisible parts are also carefully made.
