The 5g, 20g, and 30g refer to the size of the jar, not how full it will appear. Loose mineral makeup is measured by weight, not volume, and different shades can have different densities.
Because mineral pigments vary naturally, some colors are lighter and fluffier while others are more dense. As a result, the same net weight of product may look fuller in one shade and less full in another, even though the correct amount is included.
We fill each jar to the maximum practical capacity for that formula and shade, allowing room for accurate weighing, safe shipping, and easy brush swirling during use. Any extra space in the jar is intentional and helps prevent spills and product loss.
