Insole sheet by Toyo Steel, IS-350
Bonded leather insole sheets made in Germany. They are designed to protect the bottom of the 350 style boxes, including the Y-350 and T-350.
Bonded leather is an eco-friendly material made by processing post-production leather scraps into fibers, then reprocessing them into sheets by mixing the leather fiber with resin. It retains the natural texture, durability, and moisture absorption of genuine leather, but also its distinctive aging process of color changes and sheen.
Dimensions: 35.5 x 14.4 x 0.1cm.

about Toyo Steel
Founded in 1969, Toyo Steel was the first company in the world to successfully develop a technology that allows for the seamless manufacture of a steel toolbox from a single sheet of steel. A toolbox carefully crafted in Japan, durable, robust, and with a sleek aesthetic reminiscent of our grandparents' toolboxes.

about our fabrics
For the past 12 years, we've been experimenting and refining our processes to work with the best natural fibers available. We select our materials for their durability, comfort, aesthetic properties, and the conditions in which they were produced. We prioritize suppliers located near our workshop. Many of our jerseys and knits are made in Canada, while some woven fabrics come from the United States. For more specialized materials, we work with Japan and certain European countries (mainly Italy and northern countries). It is essential for us to ensure that workers' conditions are fair, and the best way to be sure is to choose countries that have a charter of individual rights that resembles ours!

made to order
If the color or size you are looking for is no longer available, do not hesitate to write to us. We have a fabric inventory at the workshop that allows us to manufacture any of our models, whether it is this one or a piece from a past collection. Simply write to us at info@atelier-b.ca with the model you are looking for so we can suggest fabrics and colors! Orders sewn at the workshop are at the regular price (if the model is on sale, the discount does not apply to a piece sewn to order). Production time can vary from 4 to 6 weeks. Items from past collections sewn to order have a 10% surcharge. We can also make alterations to the pattern, in which case there will be an additional charge depending on the situation which can vary from 10 to 20%.
