We're especially excited to introduce these napkins. Woven of pure organic cotton, they're printed with SeaInk, a pigment that's made with a base derived from seaweed (instead of the formaldehyde used in conventional inks). The factory that prints them is the first screen-printing facility in America to be GOTS certified and uses geothermal and solar energy to reduce its carbon footprint. We think they make a fun addition to the table and a wonderful gift, as well. Cold-water washing is recommended to ensure that the colors won't run.
