Each color is crafted and mulled with care, dedication, and extensive testing to ensure that they are up to every artist's standard. The pigments are chosen from the best quality, highest rated, well-known sellers, and the binder is made with pure gum arabic, water, synthetic ox gall (for paint flow), and clove oil (a preservative to prevent mold). Each half pan is labeled with a sticker that includes the color name and will come with a magnet at the bottom. The exterior is wrapped first with wax paper to ensure it stays secure, then with a foil cover and finally a outside sticker with a hand swatched label and pigment information. Each order takes about a month to create depending on how many are ordered since I am a single person small business. Made in United States of America
