Based on the provided white-background product image, generate a floss pick material explanation poster. The background is a calm light ice gray-blue, with the top left side using a thick black sans-serif line titled "Flexible Fine Line / Easily Passing Through Gaps," and the upper right side balanced the image with small print "DAILY ORAL CARE." Enlarge a white dental floss pick in the middle, keeping the thread end light blue; Below, for a simple demonstration, the floss is tightened and wrapped around a small light blue reel. The wire is straight and fine, with two downward black arrows indicating stable tension. On the left side, there's a minimalist coil icon and two lines of text: "Fine and tough, not easily loosened / More reliable for daily cleaning," without specifying kilograms or verifiable extreme tensile force data. Maintain the white U-frame and light cyan handle to adjust head curvature, handle texture, and reel shape. No brand information, no new brand or slogan. Layout with ample blank space to avoid original image values, parameter footnotes, watermarks, and obvious shadows.
