I'm looking to source high-quality 1-inch circle pins for a project, needing a total quantity of 3,000 pieces. It's essential that these pins meet strict quality standards, as they'll be used in a professional setting. Can you provide details on your available options, including materials, finishes, and any certifications that might apply? Additionally, I'd appreciate information on lead times for production and shipping. If you could share pricing details for this quantity along with any minimum order requirements or bulk discounts, that would be helpful. Looking forward to your prompt response so we can move forward efficiently!
