Cassity provides custom bag sampling and prototype development support for fashion brands, designers, and sourcing teams.
Whether you have a tech pack, sketch, reference image, or physical sample, we help review your design requirements and develop a prototype for evaluation.
From material selection and construction details to sample revisions and final approval, our sampling process helps establish clear specifications before bulk manufacturing.
Each sample is developed according to the agreed design and available materials.
For broader design development and manufacturing support, explore our OEM & ODM Bag Manufacturing services.
01 — Submit Your Design
Send your tech pack, sketch, reference images, or physical sample, together with your preferred materials, dimensions, and estimated production quantity.
02 — Technical and Material Review
We review construction feasibility, materials, components, sample requirements, and relevant development costs.
03 — Prototype Development
A physical sample is produced based on the confirmed specifications for your review.
04 — Sample Feedback and Revisions
Evaluate the sample and communicate required adjustments. Changes to dimensions, materials, construction, or hardware are documented for review.
05 — Final Sample Approval
Once the sample meets the agreed requirements, the approved version and specifications become references for bulk production.
Providing clear design information helps reduce misunderstandings and unnecessary revisions.
Useful materials include:
- Tech pack, sketch, or reference images
- Approximate bag dimensions
- Preferred material and color
- Handle, strap, and closure requirements
- Logo artwork and branding details
- Estimated bulk order quantity
- Target development timeline
You do not necessarily need a completed tech pack to begin a discussion. However, technical specifications must be clarified before the final sample can be approved.

The first prototype may need adjustments before it is suitable for production.
Common revision requests include changes to:
- Bag dimensions and proportions
- Material thickness or flexibility
- Handle length and strap positioning
- Stitching and construction details
- Zipper or hardware placement
- Logo size and positioning
Sample approval should be based on the physical product and confirmed specifications, not photographs alone.
Before authorizing bulk production, check the sample’s appearance, measurements, materials, functionality, and branding.
Use our Handbag Sample Approval Checklist to organize your review and document required changes.
Important factors include:
- Pattern and construction complexity
- Material and hardware availability
- Custom components or tooling
- Branding requirements
- Number and scope of revisions
A simple design using available materials may require less development than a new structured handbag with custom hardware.
Sample charges, revision costs, and estimated lead times should be confirmed during the project review.
