This is beautiful soft, self patterning Opal sock yarn from the Harry Potter range.  Plenty of colour, with splashes and speckles, as well as solid colour areas.  Try it and experience the fascination of a design developing on your needles.
Use it in shawl sections, hats, gloves, blankets and jerseys.  Such a versatile yarn. See pattern section.
100gms/425m per ball.  Plenty for long adult socks.  Or make hat, mitts, and socks for a child.
Shade 2355
Recommended needles 2.5mm
Machine washable.  I dry my socks on sock blockers and in the shade.
