All Velorbis leather products are created by skilled craftsmen using carefully selected materials. The leather is vegetable tanned using tannins and other ingredients found in different vegetable matter, such as tree bark prepared in bark mills, wood, leaves, fruits and roots and other similar sources. Of all the various tanning methods, the vegetable tanning is the most natural and the most environmentally friendly. The use of high quality leather wax will effectively remove most surface stains on naturally tanned leather. Some leather wax will make the leather go darker. Always try your cleaning product on a small piece of leather to ensure a satisfying result. Slight natural irregularities visible in the grain of the leather attest to its quality and authenticity, and make each piece we create unique. Please note that excessive heat, water and humidity may fuse dyes to bleed or fade. Let your leather age beautifully and naturally!
