Home / Prototype & Sample Development

Precision Manufacturing, Controlled Processes

We provide production-ready samples that accurately reflect final manufacturing standards.

Each sample is developed to validate structure, fit, color accuracy, material behavior, and surface finish, allowing brands to identify and resolve potential issues before mass production — reducing risk, minimizing revisions, and ensuring a smooth transition to scale.

Sample Types Include:

  • Acetate sheet prototypes
  • Metal optical frame samples
  • Sport & composite material samples
  • Color & engraving process samples
  • White models (RP prototypes)
  • Prototyping Process & Capabilities

    Our prototyping workflow ensures that every aesthetic choice, functional detail, and surface finish is fully validated before mass production — reducing risk and accelerating time to market.
