Cha Li Yi Shi x Little Prince Collab Thermal Bag

A magical collaboration thermal bag bringing Saint-Exupery’s Little Prince to China’s tea-delivery market, featuring fireworks, planetary wonder, and the brand’s signature romantic aesthetic.

Client Background

Cha Li Yi Shi (茶理宜世) is a Guangzhou-based fresh-tea brand that has built its identity on "Chinese Romanticism" — a nostalgic, literary aesthetic that elevates everyday tea consumption into an emotional experience. The brand's collaborations are carefully curated to align with this philosophy, partnering with artists, writers, and cultural properties that share its commitment to beauty and sentiment. The Little Prince collaboration represented the brand's most ambitious IP partnership, connecting Antoine de Saint-Exupery's timeless meditation on love and loss with the ritual of tea.
The Little Prince teaches that what is essential is invisible to the eye. Our tea is the same — the value isn't just in the drink, but in the moment it creates.
The collaboration thermal bag was released as part of a limited-edition collection timed for the New Year period, when gift-giving and emotional reflection are at their peak in Chinese culture. The bag needed to function as both functional delivery packaging and collectible art object.

Design Concept

The creative concept translates the Little Prince's cosmic journey into a tea-delivery context. Fireworks burst across the silver field like stars, while the Prince sits contemplatively on his asteroid — a visual metaphor for finding wonder in small moments. The classic Cha Li Yi Shi oval label anchors the design in brand familiarity, while the "别忘了喝年礼的茶" (Don't forget to drink your New Year gift tea) seal strip adds seasonal warmth.
Fireworks Star Field Colorful fireworks create cosmic wonder while referencing New Year celebration traditions. Little Prince on Asteroid Licensed illustration of the Prince on his planet creates immediate emotional recognition and collectible value. Silver Metallic Field Silver base color evokes starlight and lunar surfaces, creating a magical backdrop for the illustration. Seasonal Gift Messaging "别忘了喝年礼的茶" seal strip transforms delivery into gift-giving during New Year period.

Why This Design Works

Three design decisions differentiate this IP collaboration bag from standard licensed merchandise. Each leverages the emotional depth of the Little Prince property while maintaining brand coherence.
01 Cosmic Fireworks as Emotional Amplifier The fireworks surrounding the Prince don't merely decorate — they amplify the story's central theme of wonder and beauty in unexpected places. In the context of tea delivery, this cosmic imagery elevates a routine transaction into a moment of magic. Customers don't just receive a drink; they receive a piece of a beloved story. 02 Silver as Starlight Material The silver base color transforms the physical bag into a literal piece of the night sky. Unlike standard white or colored bags that merely serve as print substrates, the metallic field becomes part of the narrative — the Prince isn't printed on a bag; he's sitting among the stars. 03 Seasonal Messaging as Social Ritual The "别忘了喝年礼的茶" seal strip converts a functional closure into a seasonal greeting. During Chinese New Year, when gift-giving is central to social relationships, this message transforms the bag from delivery packaging into a cultural gesture — something customers feel good about giving and receiving.
