✅ Perfect Leveling & Centering—Every Time
✅ FREE SHIPPING
Take your grading game to the next level with the Gem10®️ Leveling Tools—the only tools specifically designed to measure both the leveling and centering of your trading and sports cards. Whether you're submitting to PSA, SGC, BGS, CGC, TAG, or another top-tier grader, these tools help you make confident, informed decisions before you send.
The Gem10 Leveling Tools combine two precision measuring instruments in one:
A millimeter-based leveling grid for accurate edge-to-edge analysis
Dual rulers, printed directly into the laminate for all-in-one measurement functionality
These aren’t your average flimsy plastic guides. Crafted from durable, thick laminate, they’re built to last—rounded corners protect both your cards and your hands, and an extra laminate overlay preserves the printed measurements and ensures long-term performance.
Gem10 pioneered the concept of leveling measurement—a tool not only to check if your card is centered, but also to identify subtle misalignments or defects across the card’s printed layers.
This tool lets you:
Measure centering and leveling of both the card and its internal design elements
Detect print layer shifts and manufacturing defects that are hard to spot with the naked or untrained eye
Evaluate borderless cards, which traditional centering tools struggle with
No other grading tool on the market gives you this level of insight.
With the Gem10®️ Leveling Tool, you’ll:
Avoid submitting off-center or unbalanced cards that won’t grade a Gem Mint 10
Catch flaws you might not see otherwise
Save money by only sending in your best, most grade-worthy cards
Whether you’re a new collector or a seasoned pro, this tool makes smart grading decisions simple.
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®️ Leveling Tools, you’ll have the tools to evaluate centering and alignment before you submit. At just $25, if this kit helps you avoid sending in just one low-grade card it’s already paid for itself, and then some.
Grade smarter. Submit with confidence. Save money.
Traditionally, collectors only had access to black-printed tools—which work great for light cards, but become unreadable over dark or black card designs.
Gem10®️ changed the game by introducing a white-printed laminate to solve this problem.
Black laminate is ideal for cards with light backgrounds
White laminate offers excellent visibility over dark or black backgrounds
Get both versions—or go all-in with the Gem10®️ King Kit, which includes every black and white leveling and centering tool in the lineup.
Every Gem10 tool is made using archival-safe, non-damaging materials to protect your cards during use. Our tools are engineered with your collection’s longevity in mind, from the precise printing to the durable laminate finish.
📦 Ships anywhere in the U.S. via USPS First Class in a secure, rigid mailer for maximum protection.
Whether you're chasing the next Gem Mint 10 or fine-tuning your eye as a grader, the Gem10®️ Leveling Tool gives you the precision, clarity, and edge you need.
