How to Insert a Card in Your SuprPetrix Phone Case

How to Use Your SuprPetrix Card Display Phone Case

Inserting and swapping cards in your SuprPetrix case takes less than 30 seconds. No tools required. Follow these simple steps to start showcasing your favorite trading cards.

Step 1: Remove the Case from Your Phone

Gently peel the case from the bottom corners of your phone. The flexible TPU frame makes removal easy without forcing. Start from one corner and work your way around.

Step 2: Place the Free Padding Insert (Recommended)

For extra heat protection, place the included padding insert into the card slot first. This sits between your phone and the card, insulating heat during charging or gaming. Every SuprPetrix case includes this insert for free.

Step 3: Slide Your Card into the Display Window

Insert your trading card (standard TCG size: 63mm x 88mm / 2.5" x 3.5") through the top slot. The card slides in smoothly and sits perfectly centered in the crystal-clear display window.

Compatible cards: Pokemon TCG, Magic: The Gathering, Yu-Gi-Oh!, sports cards (NBA, NFL, MLB), One Piece TCG, Flesh and Blood, and any standard trading card. Cards in penny sleeves (66x91mm) also fit.

Step 4: Put the Case Back on Your Phone

Align the case with your phone's camera cutout and press firmly around all edges until it clicks into place. The card is now securely displayed through the crystal-clear window.

Step 5: Show Off Your Collection!

Your favorite trading card is now on display for the world to see. Swap cards anytime by repeating steps 1-4. The top-slide design makes frequent changes easy and fun.

Tips for Best Results

  • Use penny sleeves for extra card protection inside the case
  • For MagSafe version: Simply detach the magnetic case when charging or during heavy gaming sessions
  • For valuable cards (+): Use a proxy card or common card for daily carry, keep the original in a toploader
  • Clean the display window with a microfiber cloth for the best clarity
  • Rotate your cards to match your mood, outfit, or the latest tournament deck

Frequently Asked Questions

Will the display window turn yellow over time?

No. SuprPetrix uses high-clarity display windows that are inherently resistant to yellowing. Unlike TPU cases that turn yellow within weeks due to UV exposure, our material-level solution keeps the window crystal clear for 12+ months.

Will my phone heat damage the card?

Every SuprPetrix case comes with a free padding insert that insulates heat between your phone and card. The MagSafe version is also easily removable during intensive use. Normal daily use (calls, messaging, social media) poses no risk to standard trading cards.

Can I use a screen protector with this case?

Yes, most screen protectors are compatible. If you experience edge lifting with tempered glass protectors, try one with slightly smaller dimensions or a film-type protector.

Does the case work with wireless charging?

The card adds some thickness. Standard Qi charging may not work reliably. For the MagSafe version, simply remove the case for charging. This is a common trade-off across all card display phone cases.
