Promotion & Product Details
Cost-Effective Option with Dual Color Combinations: There are 2 color matching options in total: black body with silver-white heat dissipation head / silver-white body with silver-white heat dissipation head (please note the color combination when placing an order). All customized products in our store require patience as the production process is time-consuming and labor-intensive. The appearance is processed by CNC machine tools, so there may be inevitable turning tool and assembly marks, but there will be no obvious scratches or collisions.
Important Note: This is a practical scientific research tool and instrument, not a craft! It is designed for scientific research use only. By placing an order, you agree to this note. Customers looking for crafts are not recommended to purchase! We guarantee that the performance and power of the product are consistent with the description.
