美国采购需求：天然油、卡斯蒂利亚肥皂、护手霜、护肤品

I recently purchased a product from Amazon and would like to initiate a return. The item I received, which is a type of oil, didn't meet my expectations and I'm not satisfied with it. Unfortunately, I no longer have the original packaging to facilitate the return process, which I realize may complicate things. Could you please guide me on how to proceed with this return in light of the missing box? I'd appreciate any information on alternative solutions for sending the product back. Thank you for your assistance in resolving this matter quickly.
