⚖️ Seller Warranty & Marketplace Dispute Conciliation

Activate the warranty if the L-type wrench exhibits manufacturing defects, such as cracks in the body, failure in the handle weld, or if the chrome finish peels prematurely without any misuse or improper exposure. Latent defects that prevent normal use of the tool and cannot be resolved by basic maintenance also justify warranty activation, as per the seller's warranty and marketplace return policy.
