Because that the best way to store garlic is to keep it in a well-ventilated container, the Garlic Saver is a storage solution that looks just like the real thing. The holes toward the bottom allow for air circulation around the garlic. This will keep your garlic fresher longer, usually an additional 30 -45 days. Stores 1 head of garlic. The 2 sides of the Garlic Saver attach by twist lock. Made of polystyrene plastic, these are phthalate and BPA-free. Dishwasher safe.
