Natur Design storage jar series. Beautifully organize and store your supplies in the kitchen, pantry, and cellar: Magu provides each storage jar made from ecologically sustainable and food-safe materials. The 70 percent bamboo fibers combined with grain starch are bonded with melamine resin and molded into the shape of a jar. The bamboo-melamine mixture of the jar is loosely sealed 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.
