Our Materials

Every Mahjong Press® card is printed on a premium, non-toxic synthetic stock that’s as beautiful as it is durable. We chose it not because it was easy, but because it was right.

Built to Last

Waterproof, tear-proof, and perfectly foldable, our tri-fold cards hold up to years of consistent table play. Each seam is precision-scored to stay smooth through every shuffle and deal.

Safe by Design

Made from polypropylene, a BPA-free, non-toxic material that meets RoHS, REACH, and California Prop 65 standards. It’s also PFAS, PFOS, and PFOA-free, so you can play with confidence, knowing your cards are free from forever chemicals. No PVC, phthalates, or heavy metals, just a clean, high-performance surface made for hands that play often.

Thoughtfully Recyclable

Unlike laminated paper, this material is a single-polymer design (Recycle Code #5). That means it can be recycled wherever polypropylene plastics are accepted.

Why It Matters

We built The Mahjong Press® to honor a game that deserves better... smudge-free, cleanable, water-safe, beautifully made cards that last season after season.

All materials are independently verified and certified PFAS-, PFOS-, and PFOA-free, free from harmful chemicals that can cause reproductive harm, harm to the environment, and harm to children. Compliance documentation available upon request.
