It demonstrates broad customization and ODM/OEM capabilities, including OEM service for well-known brands, but reported no new products launched in the past year, no private molds, no 3D software design service, and no SDK. Export sales account for 71%–90% of total sales. The supplier reports no inventory, overseas warehouse, showroom, overseas agent or branch, or offline trade-show participation. Lead times are stated as within 15 working days in both peak and off seasons. Raw-material traceability, contract status, digitalization, ERP integration, and AI-model status are unknown. Financial records are referenced for three years, but no sufficient evidence establishes financial credibility.
