Built for collectors
Other card purchasing channels bring many problems: high fees, fragmented liquidity, and no trust that you will actually get the cards that are advertised. Other mystery pack sites stuff their bags with undesirable floor hits and gouge their users on shipping fees, listing fees, and marketplace fees. We’ve built a platform that evokes trust and maximizes dollar value for collectors–maximal cashback with CatchBack.

We provide the mathematical proofs for randomness and publish the code for picking cards in packs. Users pick their own cards in mystery packs. We charge just $1 per completed sale in our marketplace. Users never worry about fraud, chargebacks, or faked shipping. We create the tooling for collectors to collect. Users get maximum value.

Start ripping smarter. Download CatchBack and experience the future of collecting.
