孟加拉采购需求：永久记号笔、永久墨水、编码打印机、钢笔墨水、永久性记号笔墨水、白板笔墨水

I am looking to purchase blue-colored whiteboard pens and would like to gather more information regarding your offerings. Specifically, I'm interested in the specifications, features, and any available packaging options for these pens. It's crucial for us to understand the ink quality, drying time, and whether the pens are refillable or not. In addition, can you provide details on minimum order quantities, pricing, and shipping timelines? Also, if you have any samples or catalogs available, that would be very helpful for our decision-making process. Looking forward to your prompt response so we can explore potential collaboration!
