Sincere

Tokyo / Bunkyo

A quality-management-led OEM company supporting the commercialization of contact lenses and colored contact lenses. Sincere highlights experience commercializing more than 70 private-label brands and can support the flow from consultation, meetings, lens and color design, package and blister-film design, sample creation, production, quality inspection, and delivery. Rather than positioning itself as an in-house mass-production factory, it uses partner factories in Taiwan, South Korea, and Malaysia depending on product type, then conducts incoming and product testing domestically in Japan. It is well suited to businesses that need to commercialize high-risk medical-device contact lenses with ISO 13485-based quality management, medical-device licenses, and regulatory support.
