德国采购需求：荧光笔、凝胶荧光笔、闪光马克笔、白板笔、颜料眼线笔

I recently received my latest order of your black pigment liner set, and unfortunately, I've encountered an issue: every single one of them is completely dried out. This makes them entirely unusable, and I'm quite disappointed as I've always appreciated the quality of your products in the past. I'm reaching out to see if there's anything you can do to help resolve this situation. I've ordered from you several times and have always had a positive experience, so I'm hopeful we can find a solution for this batch. Your assistance in this matter would be greatly appreciated. Thanks!
