I'm looking to source a range of pens for an upcoming project and would appreciate some details on your product offerings. Specifically, I'm interested in understanding the different types of pens you provide, such as ballpoint, gel, or fountain styles, as well as any customizations available. If you could provide me with a catalog or a list of your bestsellers, that would be fantastic. Additionally, it'd be great to know about the pricing structures, MOQs, and lead times for these products. I'm also curious about any potential bulk discounts or special promotions you might have. Let's explore how your pens can fit into our needs while ensuring quality and cost-effectiveness for both sides!
