Dec. 25, 2023 I received this as a Christmas Gift. Ravelry’s listing for Pro Lana 4-fach -- the “Fashion” line -- currently goes up to “Q”. From the colourway listing, it’s a relatively new addition to this line.

From the label (translated from the German):
“the special dyeing process always results in a matching jeans look” and “machine washable, felt-free”
