Bisfree Modular are modular food storage containers for an organized kitchen. The systematic organization of foods frees up more space in the refrigerator. There is a secret to stable stacking. The idea came from an observation that storage containers often fall down, and to avoid this, a 6mm-high edge was added to the lid. The seamless, transparent body also makes them suitable as tableware. They have excellent durability, heat- and cold-resistance, and being made of BPA-free materials, they can be used in the freezer or microwave. The silicon ensures airtightness and 99% anti-bacterial performance
