From the Skeinz website:

Check your dye pack instructions to ensure compatibility with this product naked merino possum. This yarn has a nice amount of visible possum without being too ‘furry’. It has an excellent bounce & handle & will take to colour very well. Possum fibre will come to the surface further as it is knitted.
