Riftbound before Origins, there was Project K. The original cards before launching riftbound to the public. The first cards released was the Chinese editions (riot games origin). They have sample stamped, aside from the promos and main champion card. My project K collection are from the original launch including the promo editions, some graded some raw. All are from fresh boxes/packs therefore are in clean original surface condition. All project k listings are sold as is and fresh from un-damaged boxes. Happy hunting! Will update stock and graded as I get them.
