The design of this hand warmer is based on the core concept of "cuteness and interest healing". It uses round and full pod shape as the basic outline and matches three animal roles: pink and purple rabbit (blush element with vertical ears), white rabbit (blush element with long ears) and light green frog (round eyes, smile and short limb ratio). The product creates a soft visual experience through the low-saturation Morandi color system. Each character is equipped with circular function keys (pink/purple/blue/yellow) and mini limbs of corresponding colors, forming a sense of anthropomorphic interaction. The base design uses geometric contrast (cube/hemisphere/directly standing) to enhance the scene display effect. The overall style combines the Japanese healing aesthetic and the minimalist language of modern 3C products, aiming to dispel the cold feeling of winter products through lovely design, and become a warm carrier with practical function and emotional companionship. Suggested product name: "bean warm Meng you" series (including "pink ear rabbit", "gray ear rabbit" and "green quack bean" three sub-models).
