Ona Gel Polar Crystal Topf 856g

This gel-based odor control from Ona is optimized to evenly evaporate over time to eliminate odors. Contains a complex formula of industrial grade essential oils, yet is safe to use around pets, plants and of course people. The gel dries out over time, but can be reactivated a few times with Ona Liquid.

The smell is similar to that of toilet blocks and is therefore not really suitable for living spaces.
