I'm looking for eco-friendly bubble mailers in various sizes for wholesale. Specifically, I'm interested in options that are sustainable and meet environmental standards. It would be great to know more about the different sizes available, as well as any customization options you might offer. Additionally, I'd like to inquire about your pricing structure for bulk orders and any minimum order quantities I should be aware of. Please provide details on lead times for production and shipping, as well as any certifications your products have regarding eco-friendliness. Looking forward to your prompt response!
