Delike is a relatively new Chinese fountain pen manufacturer who has been around since about 2017. They have gained a reputation for having better quality fountain pens than the cheap and cheerful ones available for a couple of dollars. However, this is also reflected in the price of their fountain pens.
They also have gained some notoriety for blatantly copying other brands these included the Delike Alpha brass fountain pen which was an imitation of the Kaweco Sport Brass Fountain Pen. Also, the Delike New Moon was a copycat of the Sailor Pro Gear Slim Fountain Pen.
