Quality control
Although we have the utmost confidence in our producers, we check our products several times before they go on sale. We always make sure that we source our dyes from an organic farm or that a residue analysis has been done. If this is not possible, we provide our customers with an analysis report of each batch. We have this tested in an independent, accredited German laboratory, according to government testing methods, for residues of pesticides and the heavy metals arsenic, lead, cadmium and mercury. In addition we test randomly for contamination with mould. We publish the results with our product images. In addition, we offer to send them by e-mail upon request.
