Should Graded Cards Be Sleeved Inside Slabs? Pros & Cons

When it comes to grading and encapsulating trading cards, one debate that frequently arises is whether or not to use an inner sleeve inside the slab. Some grading companies enclose cards in plastic sleeves before sealing them, while others, like SSINT, avoid them except in specific circumstances. But why does this matter? Let’s explore the pros and cons of sleeving inside slabs and why SSINT’s approach ensures a premium display.

Pros of Using Sleeves Inside Slabs

1. Extra Protection from Scratches & Dust
   A sleeve can provide an additional barrier against micro-abrasions and dust particles before encapsulation.

2. Prevents Movement for Oddly Cut or Thin Cards
   Some cards, particularly those with unusual dimensions, may shift inside a slab. A sleeve can help keep them secure.

3. Reduced Risk for Fragile or Vintage Cards
   Extremely old or fragile cards might benefit from the added cushioning of a sleeve to prevent potential surface damage.

Cons of Using Sleeves Inside Slabs

1. Reduced Clarity and Display Appeal
   Sleeves can introduce additional glare, ripples, or air bubbles inside the slab, affecting the visual appeal of the card. For collectors who prize pristine presentation, this can be a drawback.

2. Potential Wrinkling Over Time
   Some plastic sleeves may wrinkle or crease inside the slab over time, detracting from the card’s aesthetics and possibly obscuring details.

3. Risk of Moisture & Chemical Reactions
   Low-quality sleeves may contain chemicals that interact with the card’s surface over time, leading to potential long-term degradation.

SSINT’s Approach: Clean, Clear, and Secure Slabs

At SSINT, we prioritise providing the cleanest and most visually appealing encapsulation possible. That’s why we generally avoid using sleeves inside our slabs. Our ultrasonically welded cases are designed to fit cards securely without the need for an inner sleeve, ensuring:

• Crystal-clear presentation – No unnecessary plastic layers obstructing the view.

• A sleek and professional finish – Perfect for exhibition and display.

• Long-term security – Our cases are engineered to keep cards firmly in place.

However, in cases where we identify a risk of movement inside the encapsulation, we take extra precautions. Instead of using standard sleeves, we opt for premium Dragon Shield exact-fit sleeves, ensuring a tailored and seamless fit without wrinkles or excess bulk.

Conclusion

While sleeves inside slabs have their advantages, they also introduce visual compromises that many collectors prefer to avoid. SSINT's approach is designed to offer the best of both worlds—exceptional protection without sacrificing display quality. By only using sleeves when absolutely necessary and selecting the highest-quality materials, we ensure your graded cards remain secure, pristine, and exhibition-ready.
