Rongsheng provides OEM and ODM manufacturing support for customized leather goods and consumer accessories.

Customers can work with us based on their own drawings, artwork, reference samples, existing products, or specific product requirements. Our manufacturing and development teams then work around these requirements to prepare the product for sampling and production.

For OEM projects, customers provide the product concept, design, specifications, or reference sample, while we handle the manufacturing side of the project.

Depending on the product, we can customize materials, colors, dimensions, structures, branding details, hardware, and other components according to the approved specifications.

Our focus is to reproduce the approved product consistently during bulk production while maintaining the required quality and finishing standards.

For customers who have an existing product, reference sample, or basic product concept, we can support practical product adaptation and development.

This may include adjusting the product structure, dimensions, materials, components, or functional details to meet specific market or application requirements.

The development process remains based on the customer's product direction and requirements rather than creating a completely new fashion concept from scratch.

Depending on the project, our manufacturing capabilities can support customization of:

• Leather and synthetic leather materials
• Material combinations
• Colors and surface finishes
• Product dimensions and structures
• Stitching and construction details
• Edge finishing
• Logo and branding applications
• Hardware and functional components
• Device compatibility
• Packaging requirements

Each project begins with a clear understanding of the customer's requirements.

After reviewing the product information, we can coordinate sampling and adjustments to confirm the structure, materials, dimensions, and finishing details.

Once the sample and specifications are approved, the confirmed requirements are transferred to bulk production.

Customer Requirements → Product Review → Sample Development → Sample Approval → Bulk Production → Quality Inspection → Delivery

Our OEM/ODM manufacturing experience covers a broad range of leather goods and consumer accessories, including phone cases, MagSafe accessories, AirPods cases, wallets, card holders, laptop and tablet cases, bags, belts, and other customized products.

Each project is handled according to its specific product structure, materials, order quantity, and production requirements.

At Rongsheng, R&D and product development focus on making customer concepts practical and suitable for production.

Our development work covers product structure, materials, components, functionality, construction, and manufacturing feasibility. By considering these factors during the sampling stage, we can identify potential issues and make necessary adjustments before bulk production.

Product structure plays an important role in both appearance and manufacturing.

Our development process examines dimensions, component relationships, attachment methods, folding or forming requirements, stitching positions, and assembly methods to create a practical construction for production.

Where necessary, structural details can be adjusted during sampling to improve fit, function, durability, or production consistency.

We work with different materials according to the requirements of each product and application.

Material development may involve comparing thickness, flexibility, surface appearance, durability, texture, and compatibility with the product structure.

Depending on the project, materials may include genuine leather, synthetic leather, microfiber, fabric, felt, and other suitable materials.

Samples provide an opportunity to verify the product before moving into mass production.

Our development process can include prototype making and sample revisions to evaluate:

• Product dimensions and fit

• Structural construction

• Material combinations

• Functional details

• Stitching and assembly

• Edge finishing

• Hardware and component placement

• Overall appearance

Customer feedback can then be incorporated into subsequent sample versions until the product requirements are confirmed.

A product that works as a prototype may still require adjustments before it can be produced consistently at scale.

For this reason, our development process considers manufacturing methods and production requirements from an early stage.

Where necessary, we review material combinations, component placement, construction methods, and finishing processes to help make the product more practical for bulk manufacturing.

Our R&D and product development work is closely connected to the manufacturing process.

Once the product structure, materials, specifications, and sample are confirmed, the information can be transferred into production with clearly defined requirements.

Customer Concept / Reference → Structure Development → Prototype → Testing & Adjustment → Pre-Production Sample → Production

We do not position ourselves as a fashion design studio. Instead, our strength lies in developing and refining products based on customer-provided concepts, drawings, samples, and requirements.

By combining practical product development with manufacturing experience, we aim to create products that are not only aligned with the customer's requirements but also realistic to manufacture consistently.
