K-bank x GY Company

This custom gold bar-shaped sleeve box was created for a promotional event collaboration between Kbank and GY Company. Produced with a matte gold metallic board, glossy gold foil stamping, and spot UV printing, the package delivers the premium look and feel of a real gold bar. Its Y-style sleeve structure enhances the unboxing experience, while custom bottom and raised paper inserts securely hold promotional gifts such as the Jamggom calendar and other giveaway items. This project showcases a premium custom corrugated packaging solution for promotional campaigns, gift boxes, and branded merchandise packaging.
