This amulet's power comes from appealing to the god Njord and specifically enlisting his aid in acquiring material wealth.
Njord is the god of the sea and its inhabitants. He helps sailors and fishermen, ensuring a plentiful catch – both literally, in terms of many fish, and more broadly, a successful "catch" in endeavors and an abundance of gains. The fish itself symbolizes wealth. Njord provides a rich harvest in all senses: he helps acquire wealth, attract money, and solve financial problems.
The sea and its creatures also symbolically represent the world of imagination, with the images that reside there. Therefore, Njord can help develop fantasy, imagination, visual thinking, quick reactions, and adapt more easily to rapid changes in the ocean of business.
You can appeal to Njord for prosperity, an abundance of material goods; he helps acquire wealth, attract money, and resolve financial issues. Thus, he can be invoked for signing contracts and attracting clients. He also aids in easy and safe movement. Although Njord is responsible for water travel, he helps you move to places where there's "a lot of fish" for you, meaning finding the shortest and safest paths to locations, people, or circumstances where you can improve your material wealth.
The amulet is a thick natural leather bracelet, with the appropriate runic formula already carved inside. The bracelet is hand-painted, and the design depicts a school of fish, symbolizing wealth.
Hopefully, it will help someone catch not just a "golden fish," but certainly a truly big fish.
The amulet comes with a "visa" (likely a prayer or invocation) so that each time you put it on, you can address Njord beautifully. Gods appreciate being asked with praise and full respect, not just a simple request.
