美国采购需求：荧光笔、凝胶荧光笔、闪光马克笔、干擦马克笔、白板笔、颜料眼线笔

I've reached out three times regarding an issue with my set of pens, specifically the defective yellow pen. I initially received an email requesting my order details and address, which I provided promptly. However, I was under the impression that I could either request an exchange via Amazon or simply respond to your email for a replacement. Now, I need to update Amazon customer care with my experience, as they've requested my feedback again. It's crucial for me to convey that my issue has been resolved positively. If returning the item through Amazon is the preferred method, please let me know clearly. I'm eager to share some good news soon!
