I hope this message finds you well. I'm reaching out to inquire about your offerings regarding pure Oolong tea extract. I'm interested in understanding the various forms of extract you supply, including both bulk options and any pre-packaged products that may be available. Additionally, could you provide information on the extraction process and whether your products are sourced from specific regions known for their high-quality tea? I'd also like to know about your pricing, minimum order quantities, and any certifications your products might have. If you have samples or product catalogs, that would be great to review as well. Understanding these details will help me evaluate how your offerings align with our needs. Looking forward to your response!
