As the R&D manager of a packaging company in São Paulo, Brazil, I'm looking to source two unique hard enamel pin designs for a client. The first model is approximately 25mm in an irregular shape with either 2 or 3 colors, while the second model is around 30mm in an irregular shape with 2 colors, both made from silver metal. Could you provide a quote for each model at three different quantities: 10,000, 50,000, and 100,000 pieces? The pins should be packed in OPP bags of 20, and those bags should be further packed in boxes containing 1,000 pieces each. Additionally, please include the production lead time. Thank you!
