Natur Design storage jar series. Beautifully organize and store supplies in the kitchen, pantry, and cellar: Magu delivers each storage jar made from an ecologically sustainable and food-safe material. The 70 percent bamboo fibers combined with grain starch are bound with melamine resin and molded into the shape of a jar. The bamboo-melamine mixture of the jar is loosely topped with a round lid made of bamboo wood. To prevent any moisture buildup or sweating of the stored vegetables, all containers feature several ventilation holes at the bottom for airflow. Natur Design onion pot. This medium-sized storage jar, designed as an onion pot, clearly indicates a small but sufficient supply of onions with its distinct labeling.
