Seashells are rough when collected, but through careful hand-polishing over a long period, they shine with an astonishingly beautiful and dazzling rainbow color. Due to their beauty, they are called "opals of the sea" and are often used in jewelry such as accessories. Precious seashells are carefully used and, after intricate processing, this handmade masterpiece is created. The seashell panels have a range of overtones from green to black, red, or blue. Due to slight variations in the weight of the seashell panels involved in the production of these pens, each pen will vary slightly in weight. These are natural attributes that add beauty and uniqueness to each pen. This ballpoint pen is made from eco-friendly natural seashells. This is a limited edition ballpoint pen, unique and unlike any other in the world. This is a handmade item. Please refrain from purchasing if you are looking for perfection.
