Hi there! I'm reaching out to gather some detailed info about your product offerings. I'm particularly interested in understanding the pricing, minimum order quantities, and available customization options. Additionally, could you provide me with the lead times for production and shipping? It would be helpful to know if you offer any samples for evaluation before placing a larger order. Looking forward to your reply!
