美国采购需求：荧光笔、凝胶荧光笔、闪光笔、白板笔、干擦笔、颜料眼线笔

I recently ordered some ultra-fine tip markers and while I'm impressed with their precision, I've encountered an issue where several pens were unusable right out of the box. It's a bit disappointing since I'd like to share a positive experience, but having to toss new markers is frustrating. These markers were ordered on October 8 and arrived on October 10. I'd appreciate any assistance in obtaining replacements for the dried-out pens. Your help in resolving this matter would be greatly valued and would definitely help in making my review more favorable. Thank you for your attention to this issue!
