At the moment, our belt manufacturing system limits us to a maximum belt size of 38, but we would like to offer belts larger than that eventually, as we invest in both our machinery and facilities. Furthermore, our belt sizes are limited by the width of leather rolls and the maximum size of wood cuttings that we can get from our partners. Currently, we do not know when we will be able to offer 40+ belts. We invite you to subscribe to our newsletter to keep up with our developments.
