How to use this prompt

The word doing all the work is 'inflatable' (or 'balloon-like') — it's what puffs a flat heart into the plump 3D look; without it Flux gives you a glossy but flat silhouette. Sell the material with 'bright specular highlights': one tight hotspot top-left plus a broad soft sheen reads as plastic or gummy candy. Build the pink as a gradient — light at the top, saturated toward the bottom — because a single flat pink kills the sense of volume. Keep the contact shadow small and directly underneath so the heart reads as floating, and isolate it on pure white so you can knock the background out for stickers.

Variations to try

  • Icon set — render a matching glossy 3D star, thumbs-up, and chat bubble in the same candy-pink material
  • Red romance variant — swap candy-pink for a glossy scarlet gradient for a dating-app or Valentine asset
