Custom Bag Sample Development: From Sketch or Tech Pack to Approved Sample
We turn a sketch, a reference bag or a tech pack into a sample you can hold, check and sign off before any bulk order.
Direct answer
How Long Does a Custom Bag Sample Take?
Most custom bag samples take 5–7 days once the layout and materials are agreed, and a very simple style can be ready within hours. Samples are sewn in our own sample room, and the sample fee covers materials and labor.
Starting points
Where Can a Sample Start From?
You do not need a finished tech pack to begin.
A tech pack
We follow the file and flag anything missing.
A sketch or idea
ODM projects get a free design sketch first.
A base style
See your logo on three base styles within 24 hours.
A reference bag
We develop a new bag around what you like about it.
Common problems
Why Do Bag Samples Go Wrong?
Most failed samples trace back to something left unclear before cutting.
Before cutting
What Is Confirmed Before the First Sample?
These five items are agreed in writing before the sample room starts.
Spec drawing
Outer sizes, pockets and strap lengths.
Materials
Fabric, lining, padding and trims.
Colors
Body, webbing, zipper and thread.
Logo
Method, size and position.
Packing
Only if the sample must show it.
Sample room
Who Makes the Sample?
Samples are cut and sewn by our own sample team, next to the production lines.
Pattern
A paper or card pattern comes first.
Sewing
The sample is sewn on the same machines as bulk.
Color check
Fabric shades are compared with the card.
Revisions
How Do Sample Revisions Work?
Changes are agreed round by round, so nothing gets lost between versions.
Review
You check the sample in hand or on a video call.
Change list
We confirm each change in writing.
Next sample
The revised sample follows the agreed list.

Real project
What Does a Sample Round Look Like in Practice?
Five samples, then bulk
A US buyer reviewed five bike bag samples, visited in 2018 to approve them, then placed the bulk order.

The zipper side, the phone window edge, the top closure and the logo tab size were all settled on samples before bulk.
