I found two spools of rainbow colored line just like this a few years ago and thought they were the most beautiful readymades--and I still do! I would hang them straight on the wall from two nails--and this pair is especially nice as it appears that the line on them was never clipped, so the two are still joined, so the line could stretch between them. The line itself is really lovely, and strong, and holds its shape to some extent, so could also be used for all sorts of things should one desire.
Never used, excellent condition. 6 1/8" x 6 1/8" x 7/8" each.
