⚖️ Seller Warranty & Marketplace Dispute Conciliation

If the utility knife exhibits a manufacturing defect, such as a broken locking mechanism, a cracked body without impact, or a blade that does not align correctly in the track even after cleaning and attempting a blade change, contact support under the seller's warranty. These are defects that prevent normal and safe use of the product.
