The Modulo Jar redefines sustainable packaging with its modular and refillable design. It consists of an inner jar, an adaptable outer shell (without a bottom) and cap available in different materials. The smart structure minimizes material use, as the inner jar also serves as the base. Its flexible design allows brands to mix and match materials like glass, wood, ceramic, PP, biodegradable options, and aluminum for both the outer shell and cap. Made in Germany, it offers a premium, eco-friendly solution supporting refillable systems and customization.
