Neon Scribbles on Black Background – Vector Phone Case Sticker Prompts

Create a series of high-contrast, clean vector illustrations featuring neon scribbles on a black background. Focus on achieving sharp lines, no shading or gradients, suitable for die-cut stickers on phone cases. Use placeholders like [INSERT ELEMENT] or [INSERT SLOGAN] to customize designs for various themes, from abstract art to geometric patterns or dynamic text. The prompts should inspire bold, vibrant, and modern sticker designs that stand out with intense contrast and crisp linework.
