Copic markers are expensive due to their high-quality materials, superior performance, and long-lasting design. They use dense, vibrant alcohol-based ink that blends smoothly and retains color well over time. The markers are refillable and have replaceable nibs, making them durable and sustainable, which adds to the cost. Additionally, they offer a wide range of colors, consistent and precise application, and are imported from Japan, all contributing to the higher price. The brand's reputation and the professional- grade experience they provide also justify their premium pricing compared to cheaper alternatives.
