I'm reaching out to explore wholesale opportunities for high-quality hair products. I'm particularly interested in partnering with a vendor that has a strong reputation for quality and consistency. Could you provide me with more details about your product range, including the types of hair available, sourcing methods, and any certifications you may have that ensure quality standards? Also, it would be helpful to know about your pricing structure, minimum order quantities, and lead times for bulk orders. If you have any catalog or product samples available, that would be great for assessment. I'm looking for a reliable supplier to collaborate with, so any insights you can provide will be greatly appreciated.
