I was selling these as a set of three, but I found another one, so I'm now offering them as a set of four. The green color is causing a bloom effect and appearing as a more vibrant color in the photos, but it's actually a more subdued, understated color. They would look lovely paired with a retro obi-dome. You could even share them with a friend. I've lowered the price. They are silk. They have been stored at home for a long time, so there may be some minor imperfections. Please purchase only if you are satisfied with the condition. This price is for all four. I've lowered the price. To those who liked the listing for three, thank you for your interest. Shipping and handling fees apply. Returns are not accepted.
