I'm interested in sourcing a range of soft enamel pins, specifically around 2cm in width. Could you provide me with a detailed quote based on varying order quantities? I'm looking for options for 100, 500, and 1000 pieces, ideally in a single color. In addition to the pricing, it would be great to know about lead times, available color options, and customization possibilities. If you could also include any minimum order requirements and payment terms, that would be helpful. Looking forward to your response!
