Original Luisa Longo's precious hand-painted artwork on silk organza with mixed metallic and iridescent colors is embedded in an exclusive polyurethane solution with the softest peach-skin feel. The coasters have an extraordinary resistance to heat, abrasions, and stains, are light and totally flexible, can be washed just with a drop of water and soap. The silk organza base gives an even smoother feel and the artist's paintbrush effects and color expertise are greatly emphasized.
