Careful sorting and selection is made in choosing the wool used for LANACare products. Only wool that meets Europe’s highest certified organic standards is used. It is tested to prove that it contains no harmful substances. Fertilizing or pesticides have not been used on the fields where the sheep graze, nor have any harsh chemicals been used to wash the wool. No mulesing have been used on the sheep. Mulesing is a very criticized way of vaccination for an insect only living in Australia. The wool is as pure on the sheep as when it comes as clothing on your baby. Only the most incredibly soft & finest of this organic merino wool is selected to use in LANACare products.
