🔍 What’s Inside The King Kit - BLACK?

  • Both Black Gem10®️ Trading and Sports Card Leveling Tools 

  • The Gem10®️ Black Trading and Sports Card Centering Tool

  • Dual Functionality – Each tool combines:

    • A millimeter-based leveling grid for precision measurements

    • Built-in dual rulers for quick, all-in-one reference

    • Instruction cards for both the Centering and the Leveling Tools

đź§  Advanced Grading Support

Gem10 pioneered tools that go beyond just border centering. The Prince Kit allows you to:

  • Properly center a trading or sports card to maximize chances for success
  • Measure centering and leveling of both the card edges and its internal printed layers

  • Detect layer shifts, print defects, or misalignments often invisible to the naked eye

  • Confidently evaluate borderless cards, which traditional tools struggle to assess


🛑 Avoid Grading Mistakes & Wasted Submissions

Use The Prince Kit to:

  • Eliminate guesswork and identify cards unlikely to earn a Gem Mint 10

  • Save money by sending in only your best-aligned, print-perfect cards

  • Make grading decisions like a pro—whether you're a seasoned veteran or just starting out


🎨 Choose the Right Tool for the Right Card

Most tools on the market only come in black print, making them hard to read over dark cards. Gem10®️ changed that.

  • Black print works best with light-surfaced cards

  • White print is ideal for dark or black-surfaced cards

With the tools offered in The King Kit - Black, you’ll never be stuck with a tool you can’t read for your favorite lighter cards.


🧠 The Gem10®️ Trading and Sports Card Grading Tools: See Clearly, Grade Confidently - and Make More Money!

When evaluating dozens of cards, your eyes can play tricks on you. What looks off-center or uneven at first glance is often perfectly aligned—but without precise tools, it's easy to make costly mistakes by discarding cards that are actually grading-worthy.

The Gem10 Trading and Sports Card Grading Tools are designed to eliminate doubt and enhance your accuracy. Subtle elements like image angles, border illusions, or layered print features can mislead even experienced graders. Over time, visual fatigue only makes things worse.

Gem10 tools cut through the guesswork, helping you clearly assess centering and leveling with confidence—so you don’t overlook valuable cards, and you maximize your chances of profit with every submission.


💰 The Gem10®️ King Kit Practically Pays for Itself

Every time you submit a card for grading, you’re investing more than you might realize—on average, about $26 per card. That includes:

  • Grading fee: $20–$25

  • Postage: ~$1.00 (based on a 20-card submission)

  • Semi-rigid holder: ~$0.50

  • Penny sleeve: ~$0.05

  • Your time and effort: priceless

Now imagine submitting a card that doesn't hit the grade you were hoping for—money wasted. But with the Gem10®️ King Kit, you’ll have the tools to evaluate centering and alignment before you submit. At just $45, if this kit helps you avoid sending in just two low-grade cards, it’s already paid for itself, and then some.

Grade smarter. Submit with confidence. Save money.
