Luxury Fountain Pen with Gold Trim

[Format] Professional e-commerce product main image, square 1:1, luxurious dark-and-gold stationery advertising style with glossy black silk and elegant gold display type. [Colors] Deep black background draped in glossy black silk with soft charcoal highlights, accented by metallic gold details; the gold headline is the brightest element. No frame border. [Layout] Upper-left holds a two-line headline stack, a smaller line beneath it, then three slim gold-outlined feature pills stacked vertically. The pen lies diagonally across the right half, nib pointing to the lower left. A round gold-outlined inset circle in the lower-right corner shows a nib close-up with a gold label pill beneath it. [Subject] A glossy black fountain pen with polished gold trim: gold pocket clip, two gold cap rings, black barrel tapering to a silver iridium nib, resting on the reflective silk with warm specular highlights. [Headline] Upper left, large gold serif-style caps across two lines "TEAM CUSTOMIZATION" and "FREE ENGRAVING"; beneath it a smaller white line "Classic Upgraded Edition"; then three gold-bordered pills reading "Brass Barrel", "Push-Pull Ink Refill" and "Iridium Nib" in gold text. On the round inset at lower right, a gold pill with "Two Nib Options" in small caps. [Badges] No separate badge row; the three feature pills and the inset label carry all claims. [Mood] Premium, refined gift-stationery luxury; black silk, gold foil type and jewellery-like pen detail.
