Transparent windows or partial cut-outs can be added to showcase the colors inside, helping users quickly identify the desired palette.Inside, the tray layout can be fully customized according to the required pan shapes and sizes, such as square, round, or rectangular wells. The interior base can be designed to hold refillable magnetic pans, giving consumers the flexibility to rearrange or replace shades over time. This refillable structure supports more sustainable usage, extending the lifecycle of the palette and reducing packaging waste.For enhanced usability, optional features such as a built-in mirror, dual-layer compartments, or an applicator slot can be integrated into the design.
