Judging from the price of 50~500 you can accept, I recommend you to make one-to-one customization of high-end brand pens. Brand pen is a famous British royal brand, and the order quantity is unlimited. Can carve personalized signature, company brand, LOGO, etc. On the pen body, it can also be carved by hand. They are fashionable and full of personality.
