I'm looking to source the largest size of black diapers you manufacture. Could you please provide detailed information on the specifications, including the materials used, absorbency levels, and any unique features that set your product apart from others on the market? Additionally, I'd appreciate insights on your pricing structure for bulk orders and any available options for customization. If you have recommendations or best-selling variants in this category, feel free to share those as well. Looking forward to your prompt response so we can discuss potential collaboration!
