Thought I would share this with you all.
Saw these on TV, but bought them on ebay. The aroma supposedly lasts for up to two years. I put them on top of the refrigerator, and the kitchen smells like a vanilla cupcake. I might get the "Linen" for the bedroom or the closet. They come in glass vases too, or you can use your own little vases.
