Each shade is carefully pressed to deliver smooth application, intense color payoff, and excellent blendability.The formula can be offered in multiple finishes, such as matte, satin, shimmer, and metallic, providing endless styling possibilities.

The texture is typically smooth, with minimal fallout, and adheres well to the skin when applied with brushes or fingertips. With the addition of an eyeshadow primer, the colors can maintain their vibrancy for extended wear, resisting creasing and fading throughout the day.As an OEM product, the palette offers extensive customization options. Clients can tailor the shade range, pan layout, case color, and external packaging to fit specific branding or market needs. Options may include custom printing, logo embossing, or special finishes for the outer case. The number of colors, size of the pans, and inclusion of applicators can also be adjusted.
