Ever on the search for the perfect mandle (man + candle), these large tin candles by Nest are definitely worth a long, slow whiff of consideration. This particular one is in the scent Blue Garden which is both floral and at the same time very clean. A mysterious Southern garden after the rain. Two other scents that were instant favorites were their Mint & Moss which was so fresh and clean in a grassy way along with the deeper, perfect for the study (or man cave) Moroccan amber. Really they don't even have to be burned, simply lifting the lid fills the room. Find them here and here.
