The choice of base metal significantly impacts the pen's weight, durability, and perceived value. Brass is the premium choice for high-end corporate gifts due to its substantial weight and excellent balance. Stainless steel offers superior durability and resistance to corrosion, making it ideal for daily professional use. For budget-conscious bulk orders, aluminum provides a lightweight and cost-effective alternative. Ensure the surface finish—whether electroplated, lacquered, or matte anodized—is thick enough to withstand frequent handling without peeling.
