Sold as a set of four pillowcases, not sold individually. These silk pillowcases (18 in x 18 in) are in shades of green. It was difficult to photograph the colors well, so I've described them here from top to bottom of the cover photo: one is a light celery shade, next a yellowish green that appears more chartreuse when the light hits it right, next is a gentle olive shade that has elements of burgundy when the light hits it right, and finally a light spring leaf green. Zipper closure, no lining inside. Never used, NWOT Jim Thompson is a Thai silk brand famous for traditional and modern designs.
