# You’re the Proof of Purchase | No. 070, Unisex T-Shirt

Concept:  
Inspired by receipts, barcodes, and moments that validate who we are, this design nods to consumer culture, existentialism, and the need for recognition. “You’re the Proof of Purchase” is both tongue-in-cheek and deeply resonant — a wearable stamp of identity for anyone who’s ever searched for meaning in the everyday.  
  
Product Description:  
A playful yet poignant take on self-worth and validation, this shirt mimics a classic receipt aesthetic with the phrase “You’re the Proof of Purchase” stamped proudly. It’s perfect for those who find humor in introspection, question systems, or just really like receipts. Printed on a neutral base to evoke paper tones and minimalism.  
  
Inner Collar Quote:  
“Authenticity Verified | 本物保証”
