Glossy Black Plastic Bag Logo Mockup

Photorealistic studio product shot of a single glossy black plastic merchandise bag standing upright, full and slightly bulging, centered on a clean solid white background. The bag is tied tightly at the top with gathered wrinkled plastic forming a knot and a ruffled neck. Realistic crinkles, folds, shiny highlights, and stretched black polyethylene texture throughout. Front and center, a crisp flat white screen-printed custom logo designed as a carnival-style badge: an outlined banner, geometric emblem, small stars, the bold playful text "[ARCADIAS]" with an arch shape incorporated into the wordmark, and the curved tagline "[LA ESQUINA DIVERTIDA]" underneath. Soft, even studio lighting with a subtle floor shadow, high contrast, perfectly centered, with no hands, clutter, or background elements.
