I'm looking to source cup lumps for our upcoming production needs. We're particularly interested in understanding the specifications, including the size, quality standards, and any relevant certifications your product adheres to. It's essential that the material meets our requirements for durability and performance. Additionally, I'd appreciate it if you could provide information on your pricing structure, available quantities, and the lead time for delivery. If there are any samples available for testing, please let me know, as this will help us assess the product quality before making a larger commitment. Looking forward to your prompt response!
