The Oberland Collection is crafted from 100% cowhide leather. This leather can usually be cleaned with the use of a soft cotton cloth slightly dampened with distilled water (sodium-free seltzer water may be substituted) and a mild bar soap, applied in a circular motion. Repeat with distilled water only to ensure no residual soap remains. The leather should then be allowed to dry completely.This collection requires no creams, polishes, or leather conditioning products to maintain its beauty. Vacchetta leather will darken over time and with exposure to light.
