Simple 3" x 3" ONA Blocks are great for small, enclosed areas prone to developing less-than-pleasant odors. They're great for cars, boats, closets, lockers, bags, trash and recycling bins, or any place that could stand to be deodorized.

Do you have a smelly pail? To solve that problem, simply remove the lid from the block and place in the bottom of the pail. The unpleasant odors are gone - quickly and easily. The best part is that the active ingredients in the ONA Blocks are plant based, and therefore safe to use around people, plants and pets.
