The Prepara Herb Savor will maximize the longevity of your fresh herbs so you can make delicious, healthy meals at home. To use, simply rinse and pat dry your herbs of choice and place them inside the Herb Savor pod. Close the front cover until it snaps into place, so that your herbs are kept firmly in place and add fresh water to the reservoir through the removable filler cap. The herbs inside will draw the water up from the base through their stems, so they stay fresh longer. You can also use the Herb Saver to store asparagus. The BPA-free Herb Savor features a transparent window so you can quickly identify your herbs, and a rigid construction that keeps delicate leaves protected. Plus it's 100% dishwasher safe. Simply remove the transparent cover and place both pieces face down in your home dishwasher.
