Your team has chosen the finish. Have you also defined the reference for the next order?
For nail brands, an approved effect sample is more useful when the conditions behind it travel with the approval.
A photograph can communicate a direction. A labelled physical tip, paired with a short application record, gives purchasing, development and supplier teams a clearer starting point for comparison.
Before closing a sampling round, build a simple reference set:
- The selected sample: Record the supplier’s sample code and your internal project reference.
- The application record: Note the base colour, formulation or application system, preparation method and finishing top coat.
- The visual reference: Keep labelled photographs and a short movement video under documented lighting.
- The approval scope: State what was accepted visually and which formulation or finished-product checks remain open.
Keep the reference accessible to whoever handles the next purchase—not only the person who reviewed the original samples.
When a later sample looks different, compare the recorded conditions before drawing conclusions about the pigment. A visual difference is a reason to investigate; it does not, by itself, identify the cause.
At Yiwu Bojun Pigment, I help nail brands turn effect ideas into focused powder-sampling discussions. Suitability still needs evaluation in the intended formulation, application and top-coat system.
Would a simple sample-reference checklist be useful for your next development project?
