The handles on both sides are easy to carry and provide ventilation and moisture resistance, keeping your potatoes, garlic and onions fresh longer.The gases given off by the onions can cause the potatoes to sprout faster. Some people prefer a separate potato bin for this reason. The nice thing about this bin is that the compartments are completely separate. There in no airflow between the two compartments, so it keeps those onion gases away from the potatoes.A potato storage bin, similar to an onion storage bin, is a reusable storage container made specially to store potatoes. These bins provide the same purpose for potatoes that a bread box does for bread- keeping them good for as long as possible.
