I'm really interested in your frosted white glass jars with bamboo lids, specifically the cream jars in various sizes. Before I place a larger order, I'd like to request samples of these sizes if possible. Can you confirm whether the jars and lids are food-grade certified? Also, do the jars have any internal coatings to prevent interaction with oils or essential oils? Additionally, I'm curious if the bamboo lids have a moisture-resistant treatment, and whether you can provide airtight seals or liners for better product stability. Do you offer customization options like logo engraving or jar printing? What's your minimum order quantity for bulk purchases? I'd also appreciate insights on shipping samples to Europe and the potential for sending bulk orders directly to my manufacturer. Lastly, please let me know the sample costs, including shipping, and the payment process. Thanks!
