Remove foul odours naturally – use ONA Blocks.
They don’t just mask odours - they neutralise odours using an essential oils based formula that seeks and destroys organic and non-organic odours, replacing it with your choice of scent.
Simply remove the lid and let the active ONA ingredients evaporate and neutralise any odours they come into contact with, permanently and efficiently. It’s as easy as that.
