I'm looking to gather detailed pricing info on polyamide elastane material. Specifically, could you provide the cost per yard in Indonesian Rupiah (IDR)? It would be great to know if there are any quantity discounts or minimum order requirements. Additionally, please include any relevant details regarding the quality and specifications of the material. If there are samples available or other options, I'd love to hear about those as well. Looking forward to your prompt response!
