When customizing rum bottles, you have a variety of options to choose from, including custom shapes, embossing or debossing, silk-screen printing, and labeling. You can also opt for surface treatments like frosted, painted, or textured finishes to add a unique touch. For a more premium look, colored glass and custom closures, such as corks or custom caps, can further enhance your bottle’s design. Additionally, custom outer packaging, such as gift boxes, can complement the bottle and elevate your product’s presentation.
