The white matte texture of the pen bodies is clearly visible, with full, distinct details of the blue color-selector key and red color-selector button on the side of each pen. The background is a solid dark gray low-tone backdrop, with a fixed close-up shot that clearly presents the side-by-side exterior details of the two pens.

Shot 3:
  - Duration: 3.0sec - 4.5sec
  - Scene Type: Product highlight showcase
  - Scene: A particle convergence special effect appears first, as the outlines of two pens gradually take shape from tiny scattered light points. Then a hand wearing a black textured glove steadily holds one white 3-color pen, with the pen suspended in mid-air above the palm for display. A prominent white brand product title text pops up at the bottom of the frame. The camera gradually focuses on the pen held in the hand as the particle convergence process unfolds, maintaining a close-up perspective throughout.
Shot 4:
  - Duration: 4.5sec - 6.5sec
  - Scene Type: Ease of use demonstration
  - Scene: From a first-person perspective, a hand holding the 3-color pen sequentially draws black, blue, and red wavy lines on a notebook page printed with black grid squares. After finishing each color, a large, eye-catching single Chinese character label for that corresponding color pops up, accompanied by a small square icon of the matching color. The camera moves steadily following the writing trajectory of the nib, accurately capturing every smooth ink flow stroke.
  - Subject: Làm bài sửa lỗi.
Shot 5:
  - Duration: 6.5sec - 10.5sec
  - Scene Type: Usage scenario setup
  - Scene: The camera cuts to a page of a math exercise book. The hand holding the 3-color pen first uses the black nib to write and solve a problem on the exercise, then switches the nib color to use the red nib to mark revision notes next to the question, then switches again to the blue nib to write comments in the blank space of the exercise. During each different color operation, large Chinese function characters of the corresponding color pop up at the top of the frame. The nib writing movements are continuous and smooth, and the camera always stays focused on the contact point between the nib and the paper, moving slightly in tandem with the writing action.

Shot 6:
  - Duration: 10.5sec - 15.0sec
  - Scene Type: Product performance demonstration
  - Scene: The camera cuts to a plain white paper frame, simulating the stuttering, ink-starved writing effect of an ordinary multi-color pen, where the nib drags across the paper leaving broken, intermittent ink marks. Then the camera cuts to a close-up of this 3-color pen writing, where the nib draws continuous, smooth black spiral lines across the paper with even, unbroken ink flow. The shot transitions smoothly from the close-up of the stuttering nib to the macro shot of the nib writing flawlessly.

Shot 7:
  - Duration: 15.0sec - 19.5sec
  - Scene Type: Product material showcase
  - Scene: Three pen refills of different colors are placed side by side on a solid black matte background. The metallic bullet-point nib structure is clearly visible with distinct reflections. The white Chinese label '子弹头' pops up on the frame, then the camera cuts back to the 3-color pen nib writing footage, where the nib draws continuous, dense spiral lines on white paper with even, smooth ink flow and full, complete strokes. The shot first uses a fixed close-up to display the refill details, then moves steadily following the writing trajectory of the nib.

Shot 8:
  - Duration: 19.5sec - 25.0sec
  - Scene Type: Product design highlight showcase
  - Scene: The camera zooms in on the rear hollow cavities of the three pen refills. The tube cavity of the black pen refill is noticeably thicker and larger than the red and blue refills, demonstrating the large-capacity ink reservoir design. Then the frame cuts to the nib writing calligraphy-style strokes on blank paper, with rich, saturated ink and sharp, clean stroke edges. The shot first focuses on the rear tube cavity of the refills to show the capacity difference, then the camera moves slowly following the writing motion of the nib.
