英国采购需求：热烫金箔、冷烫金箔、数码烫金箔、颜料烫金箔和特种箔

I'm interested in sourcing hot stamping foil with dimensions of 64mm by 120mm. Specifically, I'm looking for both gold and silver options that feature a double-sided finish. It's important for me to get high-quality materials that will meet my production needs. Can you provide information on availability, pricing, and any minimum order quantities? Additionally, I'd love to know about the ordering process and shipping options. If possible, please send me samples of the foils for evaluation before I place a larger order. Understanding your product specifications and lead times would also be beneficial. Looking forward to your prompt response, as I'm keen on moving forward with this procurement.
