It all starts with the fragrance. Trapp saturates each candle with perfume to ensure it will fill a room with fragrance from the very first time you light it until the wax is gone. They select the finest fragrances available world-wide. Then combine those fragrances with their custom blend of wax –fully-refined paraffin and soy wax – matched with lead-free wicks to minimize soot and ensure the perfect burn.
