Quality Control (QC) is the most critical step in the oopbuy spreadsheet buying process. Before your order ships from kalobuy.com, you need to inspect photos of the actual product to confirm it meets your expectations.
This tutorial covers everything you need to know about QC: requesting inspection photos, reading seller QC standards, identifying common defects, and knowing when to approve or reject an item.
Mastering QC will save you money and disappointment. The oopbuy spreadsheet includes seller QC ratings to help you choose sellers who consistently pass quality checks.
What is Quality Control (QC)?
Quality Control is the process of inspecting product photos before shipment to confirm the item matches the listing and meets quality standards.
When you order from kalobuy.com, the seller sends the item to a warehouse where QC photos are taken. These photos show the actual product from multiple angles, including stitching, tags, logos, and materials.
You review the QC photos and decide whether to approve or reject the item. If approved, the item ships to you. If rejected, you can request an exchange or refund.
The oopbuy spreadsheet tracks seller QC ratings based on real buyer feedback. Sellers with 4.5+ QC ratings are recommended for quality-sensitive orders.
How to Read QC Photos
Check Overall Shape
Look at the overall silhouette of the item. Shoes should have the correct shape, hoodies should have proper proportions, and accessories should match the listing dimensions.
Inspect Stitching
Zoom in on stitching lines. Clean, straight, and consistent stitching indicates good quality. Loose threads, crooked lines, or skipped stitches are red flags.
Verify Tags & Labels
Check tags, labels, and logos against the listing. Authentic products have specific tag placements, fonts, and material codes. Compare with the reference photos.
Check Materials
Examine the material texture in the photos. Leather should look smooth, cotton should look woven, and synthetic materials should have consistent patterns.
Compare to Reference
Always compare QC photos to the listing reference photos. Look for differences in color, shape, logo placement, and overall quality.
Common Defects to Watch For
| Defect Type | Description | Severity | Action |
|---|---|---|---|
| Stitching Errors | Crooked, loose, or skipped stitches on seams | Medium | Reject if obvious |
| Wrong Tags | Incorrect label, missing tag, or wrong font | High | Always reject |
| Color Mismatch | Product color differs from listing photos | Medium | Reject if obvious |
| Logo Issues | Logo placement, size, or quality is wrong | High | Always reject |
| Material Problems | Wrong material, thin fabric, or poor quality | Medium | Reject if poor |
| Size Errors | Item size does not match the ordered size | High | Always reject |
