I hope this message finds you well. I'm reaching out to request your assistance with a matter regarding the glass products we've sourced from your company. We need to confirm the material composition for compliance purposes. Specifically, we require a formal declaration stating that the glass in question is made of Soda Lime Glass. Providing this declaration is crucial for our quality assurance and regulatory needs, so your prompt attention to this matter would be greatly appreciated. If there's any additional information or documentation you need from us to facilitate this process, please let me know. Thank you for your support!
