Use the attached product image with a white background as the sole reference; the product’s appearance must remain strictly identical. Fully preserve the slender, pearlescent‑white cylindrical handle with its slightly flattened front, the single flush‑mounted, round, brushed‑silver button, the delicate satin‑finish silver neck ring, the narrow, gradually tapering white brush neck, the compact oval brush head, the densely packed, soft white bristles tipped with a pale ice‑blue hue, and the narrow matte‑silver base ring—maintaining the original proportions, structure, materials, and colors. No redesigns, color changes, additions or deletions of components, nor the incorporation of symbols, scales, text, or branding are permitted. Create a realistic, high‑end vertical‑format commercial poster for an electric toothbrush: employ a clinical white palette paired with an ultra‑light, cool gray tone to evoke a high‑key studio atmosphere. Introduce a novel composition featuring a low, transparent, circular laboratory glass table, a vertically offset, finely grooved glass panel, and, in the distance, a small, scale‑free, transparent beaker, while maintaining ample clean negative space. Position the product at a three‑quarter angle from the front, as depicted in the white‑background image, standing upright on the glass table from bristles to base. Complement this with neutral, cool‑toned soft lighting, precise polymer and glass highlights, subtle vertical reflections, and authentic contact shadows. The inclusion of chargers, spare brush heads, toothpaste, splashes of water, other products, people, text, brands, logos, symbols, scales, or watermarks is strictly prohibited; the product must not be cropped.
