No chemicals, perfumes or dyes are used to make them. Each ball is hand crafted using only Merino, Polworth or Corriedale wool - depending on the colour. They are tested to last for 500+ loads. Simply store them in your dryer between loads.
Available in natural colours (no dye) brown, grey or white. The colour does not affect the performance in any way and will not transfer to the clothes as it is the natural sheep's natural colour.
