One small skein of discontinued ribbon yarn by Berroco called Zen Colors. This (full) skein weighs 1.75 ounces (50 grams) and is 110 yards long. Ravelry lists this as an Aran/Worsted/4 yarn. Berroco dodges the question, so we'll go with 4.
The fiber content is 55% cotton, 45% nylon. It's nice and soft. The colorway ("Mindfulness," color #8170) is like a muted, soft rainbow, and the yarn is half shiny, half matte.
Sorry, I've just got one skein of this gorgeous yarn.
Please send me any questions you may have, and thanks for looking.
