What is QC in Oopbuy

QC stands for Quality Control. Before shipping, sellers send photos of your actual product. You inspect these photos for accuracy, stitching, materials, logos, and overall quality. Based on the photos, you decide to GL (approve) or RL (reject) the item.

How to Inspect QC Photos

Look for these key elements in QC photos: logo placement and embroidery, stitching quality, material texture, color accuracy, sole patterns for shoes, and packaging details. Compare with retail images from official stores. The oopbuy spreadsheet includes retail reference links for comparison.

GL vs RL Decision Guide

GL means the product looks good and you approve shipping. RL means flaws are unacceptable and you want an exchange. Common RL reasons include major logo flaws, wrong colors, poor stitching, and damaged items. Minor flaws that are unnoticeable when worn are usually GL acceptable.
