Creative Phone Case Sticker Design: Bear with Heart-Shaped Sunglasses

Design a clean, vector illustration of a bear wearing heart-shaped sunglasses. Focus on high contrast, bold outlines, and no shading or gradients, for a perfect die-cut sticker. Use the placeholder [Bear-Head] for customizing expressions or accessories. Ensure the final design is playful, charming, and suitable for printing on phone case stickers, with a pure white background and high visual impact.
