英国采购需求：安全带

I'm looking to gather some detailed information about your safety harness options, specifically the largest size you offer. It would be great to know the specifications, materials used, and any special features that set your product apart. In addition, could you please provide the pricing for this harness, along with the estimated delivery time to the UK? Understanding your shipping terms and any potential bulk order discounts would also help in making a decision. Thanks!
