This yarn was sold in the Shanghai area in 2001. It is not known whether it is still available.

Laundry symbols on label indicate: hand wash; do not bleach; do not tumble dry; medium iron; Dryclean, any Solvent Except Trichloroethylene.

It’s slightly thinner than 4ply, but closer to 4ply than 3ply. Apparently in China the weights are thick, medium and thin yarn, so this is thin yarn.
