The IP of "Treasure Hunting Notes"

Guangdong Sihan Printing & Packaging partnered with The Lost Tomb IP to launch limited-edition collector cards featuring iconic characters like Zhang Qiling and Wu Xie. Leveraging 3D embossing and gold foil stamping, Sihan recreated intricate details (e.g., Zhang’s signature tattoos, ancient tomb motifs) with UV-cured inks for vivid color reproduction. The team produced 30,000 sets within 3 weeks, incorporating “hidden rare cards” (signed by voice actors) to drive fan engagement.

Results: 95% of card sets sold out in 48 hours, social media (#TombNotesCards) garnered 2.1M impressions, and Sihan secured a 2025 extension to add AR-enabled cards. This collaboration solidified Sihan’s reputation for merging IP storytelling with premium print craftsmanship.
