Pros
1 YEAR WARRANTY: Any problems with the nuts, you can rest assured of our worry-free REPLACEMENT or RETURN service. NOTES: Sturdy one-piece structure, triple nickel and chrome plating, made of heat-treated steel, which can effectively prevent rust, but for long-term use, please lubricate and clean the product regularly.
