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 recently bought a set of wet erase markers online, and I have to say, I'm really disappointed. After just a few minutes of use, several markers have already stopped working, which is frustrating because I expected better quality. Could you please help me resolve this issue? I'm looking for solutions or recommendations for markers that actually perform well. It's important for me to find reliable supplies, so any guidance you can provide would be greatly appreciated. Thanks in advance!
