Calais cocoons are made of three strands of twisted mercerised cotton. They are presented in small cocoons of 5 grammes (approx. 110 m) making them pleasant and easy to use.
Calais cocoons comprise three strands (professionals use the term "ply" for strand). The thickness corresponds to a N°80 from DMC. All the colours can be bought individually or in boxes of 12 per same colour.
