INCREASE THE VALUE OF YOUR COLLECTION

Each certified piece receives an authenticity report and a note on its conservation status, as well as a universal registration number.

For the collector, it is a secure way to professionalize their collection, keeping it private, but with certified proof of its value and rarity.

For the future, it is a guarantee as a legacy, investment, documentation for an auction house, or peace of mind for a future buyer.

PROTECT YOUR COLLECTION

Each encapsulated piece is sealed and registered with its conservation grade.

For the collector, it is a guarantee that the piece is protected and prevents its degradation due to handling, humidity, dirt, photodegradation, or air exposure.

For the future, it is a "time capsule" that maintains the piece at its maximum potential, and therefore, increases its value in the collector's market.
