Ona Blocks are great for smaller areas like closets, attics, boats, kitchens, cupboards, gym bags, and so on. Basically, any tight space you have an undesirable odor and want to get rid of it. All you have to do is remove the cap or punch a few holes in it and pop it wherever your odor is. The Block is 3" x 3" and fits most anywhere. It will release odor neutralizing compounds until it is spent. Replace as needed.
