### 💡 QC Insight for Buyers Sharp points on small metal components like O-rings are a critical safety hazard, especially for items intended for children or daily handheld use. Beyond simply “instructing workers,” we highly recommend that you require the supplier to source pre-polished or deburred O-rings directly from their hardware sub-supplier. This shifts the quality control burden from the manual assembly line to the component manufacturing stage, where it is far more effective and cheaper.
