A one-time-use concentration enhancing bracelet is provided, which strengthens the concentration power and improves the studying faculty and working efficiency. A one-time-use concentration enhancing bracelet has structure of three layers including the solid aroma(a), the non-woven fabric(b), and the fabric(c). When the solid liquid fragrance is used up, only the center of the non-woven which is the upper layer becomes hollow. Therefore, the presence of the liquid fragrance can be easily confirmed. Since the fabric delivers the heat well, it contributes to the fast diffusion of aromatic molecules. |
