This fibre is Bamboo Top.  "Top" means that it has been combed and the fibres are all aligned parallel.  There are no bumps or noils in this preparation.  Characteristics of bamboo are that it is anti-bacterial and eco-friendly. 

It is amazing that this beautiful fibre comes from a bamboo plant.  It is very soft and has a gleaming shine.  Ply it with your wool or other fibre for a bright strand  in your hand-spun.

This fibre also may be used for paper-making.  You get paper with the shine of bamboo in it.
