I am interested in applying a high-quality Golden PVD treatment for stainless steel screws in a specific size. For the initial order, I'm looking at approximately 4,000 pieces. It's essential for us to ensure durability and visual appeal, so I would like to know if you can accommodate this request. Additionally, could you provide information on the various thickness levels available for the Golden PVD treatment? Understanding the differences and benefits of each option will help us make an informed decision. I appreciate your prompt response regarding these details. Thank you!
