Our pigments and Micas are all sold by weight. We make every effort to present the true color of the product. However, color may vary depending on the material, camera used, and/or the device used to view the product. The buyer assumes responsibility for the product once purchased. Due to the nature of the manufacturing and packaging process cross-contamination is possible, though every effort is made to avoid it. Once received it is the buyer’s responsibility to use the product correctly to ensure the most optimal outcome.
