A production partner for brands, designers and fashion companies
Third-party handbag production is designed for companies and professionals who want to create bags with their own brand, relying on a specialized manufacturing partner.
Castellari Diffusion works with:
- established fashion brands;
- independent designers;
- fashion startups;
- companies that want to create a line of accessories;
- businesses interested in private label products;
- professionals with an idea, a drawing or a sample to develop.
Each project is carefully evaluated, because every collection has different needs in terms of materials, finishes, quantities, style and market positioning.
From drawing to finished product
The production process starts by listening to the client.
We can begin from a drawing, a technical sheet, an existing sample, a moodboard or even from an idea that still needs to be developed. Castellari Diffusion analyzes the request and supports the client in defining the product.
Project analysis
We evaluate the type of handbag, dimensions, functionality, desired materials and production goals.
Prototype development
We create a first model to check proportions, structure, technical details and final appearance.
Review and refinement
The prototype is reviewed and, when necessary, adjusted to achieve a result that is consistent with the client’s expectations.
Sampling and production
Once the model has been approved, the project can move forward to sample production or final manufacturing.
Made in Italy production
Choosing Made in Italy production means giving value to quality, craftsmanship and attention to detail.
In handbag production, every element contributes to the final result: material selection, cutting, stitching, metal accessories, linings, finishes, proportions and quality control.
Castellari Diffusion makes its experience available to create refined products that are consistent with the identity of the brand.
Customized handbags for your brand
Third-party production allows the client to develop customized handbags with their own style and brand identity.
Different elements of the product can be customized:
- shape and dimensions;
- materials and colors;
- internal linings;
- metal accessories;
- handles, shoulder straps and closures;
- custom details;
- client logo or brand application;
- packaging and product presentation.
The goal is to create a handbag that reflects the client’s project and is suitable for its target market.
