A wish box can be used Almost like a manifestation box. But it's for wishes. You can either write out your wishes and place them in the box, or use symbolic images.
Or after a particularly stressful day —open the box and speak your wishes into it, then close the box and let the universe take care of the rest. This has the magick of the Djinn placed on it. there is no Djinn in the box however, just the power they possess.
