90s Aesthetic Collage Stickers: Rollerblades & Cassette Tape

Create a vibrant, clean vector illustration featuring a *[rollerblades]* and a *[cassette tape]* in a 90s retro collage style. The design should have sharp, high-contrast outlines with no shading or gradients, set against a pure white background. Focus on detailed line work that captures the nostalgic essence of 90s skate culture and music culture, perfect for die-cut sticker formats. Incorporate additional 90s elements like geometric shapes or stars if desired, but keep the composition balanced and clean.
