What is a card display phone case?

A card display phone case is a phone case with a built-in transparent window that lets you showcase your favorite trading card (Pokemon, MTG, Yu-Gi-Oh, sports cards) on the back of your phone. SuprPetrix offers two lines: standard cases (PC construction, 50+ phone models) and MagSafe magnetic card holders (rigid anti-yellowing TPU, wireless charging compatible).

Will the card display window turn yellow?

Our MagSafe magnetic card holders use rigid (hardened) TPU, which resists yellowing and stays crystal clear for 12+ months. Our standard (non-MagSafe) phone cases use PC (polycarbonate), which may gradually lose clarity over extended use — we offer affordable replacement display inserts for easy refresh.

Which phone models are compatible?

SuprPetrix card display phone cases are available for iPhone 11 through iPhone 17 series (including Pro, Pro Max, Air), Samsung Galaxy S24/S25 series, and select Pixel models. We also offer MagSafe-compatible versions.

What size cards fit in the case?

Our cases are designed for standard TCG card size (2.5" x 3.5" / 63mm x 88mm), which fits Pokemon, Magic: The Gathering, Yu-Gi-Oh, and standard sports cards. Cards in penny sleeves also fit perfectly.

Will the phone heat damage my card?

Every SuprPetrix case comes with a free padding insert that effectively insulates heat between phone and card. The MagSafe version is easily removable — just take it off during heavy gaming or charging. Normal daily use poses no risk to cards.

How do I change the card?

Simply remove the case from your phone, slide out the current card from the top slot, and insert your new card. The process takes less than 30 seconds. No tools required.

Do you ship internationally?

Yes! SuprPetrix ships worldwide. US orders typically arrive in 7-11 business days. International orders take 7-20 business days depending on region. Free shipping on orders over $50.

What is your return policy?

We offer a 30-day return policy. If you're not satisfied with your purchase, contact us at service@suprpetrix.com for a full refund or exchange. Items must be in original condition.
