From the Spinneybeck Website:
Velluto Pelle is a lightly enhanced aniline dyed leather. The light enhancement process refines the surface of the leather without penetrating the dermis of the hide. The combination of the lightweight material, subtle surface enhancement and special ironing process creates the suppleness and smoothness of Velluto Pelle. This enhanced grain product closely approximates the luxurious hand of Sabrina for price-sensitive projects.
