Size & function
Check proportions, openings, storage, straps and intended use.
ULOVEBAGS / OEM & ODM BACKPACKS
A sample you can measure, use and review.
Pictures help communicate a direction; a physical sample helps you judge the result. Review storage, fit, fabric and finishing before settling the version you want to manufacture.
What the sample helps you review.
Materials & finish
Review hand feel, color direction, lining, padding and workmanship.
Branding & details
Check logo effect, placement, components and label information.
Sample terms are confirmed for your project.
Reference sample time is 1–7 working days. Share the style, materials, artwork and requested changes so we can confirm the sample arrangement, fee and schedule. Record any revisions before approval; production timing is reviewed separately.
Send a clear sample request.
Provide reference images or drawings, approximate dimensions, required compartments, material direction, artwork, estimated bulk quantity and delivery country.
You do not need to have every technical detail ready. Tell us what is essential, and we will identify the remaining decisions before development starts.
How sample approval works.
01
Review the brief
Check feasibility, material availability and the sample scope.
02
Confirm the arrangement
Agree the fee, courier responsibility, expected timing and any special sourcing.
03
Develop & review
Evaluate the sample against the agreed product requirements.
04
Record revisions & approve
Consolidate comments and confirm the final version before bulk production.
Make revisions easy to follow.
Use marked photographs, drawings or a numbered change list. Identify dimensions, components or appearance details precisely. Any effect on materials, cost or timing is reviewed before another sample is made.
Use an approval checklist, not a general impression.
| Decision | What to confirm |
|---|---|
| Size & storage | Measure the main body, important openings and internal sleeves against the agreed dimensions. |
| Carrying details | Review strap adjustment, handle length, padding and attachment positions. |
| Materials & color | Check the outer fabric, lining, webbing and visible components together. |
| Branding | Review artwork size, position, color and the selected application method. |
| Packing direction | Confirm labels, hangtags, individual protection and information required for bulk packing. |
Review the sample as a working backpack.
Open each compartment, operate the closures and review the intended storage arrangement. Mark requested changes on photographs or a numbered list so dimensions, functions and visual details can be discussed separately. Confirm the revised reference before bulk production.
Clarify what is approved and what is still open.
If a sample uses a temporary color or component because the production item is unavailable in sample quantities, record that difference explicitly. Approval of the construction should not accidentally approve a substitute material.
Keep the final approval and agreed changes together with the product specification. Additional samples and revisions may affect development cost and timing, so these are reviewed before further work.
SAMPLE REVIEW CHECKLIST
Give feedback that can be built into the next sample.
Check overall size, usable compartments, strap adjustment, fabric feel, logo position and opening access. Combine comments into one marked-up set of photos and distinguish required changes from optional ideas.

BUYER QUESTIONS
Before you place
an order.
Is the sample always free?
No. One sample fee may be waived for a qualified project after review. Courier charges and special development expenses are confirmed separately before work begins.
Will the sample use the intended production material?
The intended materials are used when available in sample quantities. If a proposed substitute is needed, it is explained before sampling and must be reviewed before bulk approval.
Can I request multiple colors or versions?
Yes, the scope can be discussed. Additional samples, revisions or special components are reviewed and priced according to the development work required.
