PJU 3×4 Hard Card Sleeves 400-Pack — 200 Rigid Holders + 200 Soft Inners, Anti-Scratch Protection for 2.5×3.5 Trading Cards

PJU 400 Card Sleeves deliver a dual-layer protection system—200 rigid 3"×4" hard sleeves plus 200 soft inner sleeves—to keep sports and trading cards safe, flat, and clearly visible.

Whether you're building a display, preparing cards for storage, or shipping prized pieces, these sleeves combine a firm outer shell with a smooth inner slip to reduce scratching, bending, and exposure to moisture and fingerprints. The pack is designed to fit standard trading cards (baseball, basketball, Pokémon, Yu-Gi-Oh!, MTG, and many K-pop photo cards), offering collectors and sellers an affordable way to protect large quantities at once.

How do the hard and soft sleeves work together to protect my collection?

The system uses a soft, low-friction inner sleeve that cushions the card and prevents surface scuffs, plus a rigid outer sleeve that maintains card flatness and resists bending during handling or shipping. This layered approach reduces contact damage while keeping edges and corners intact.

• 200 soft inner sleeves (2.6"×3.6") prevent scratches and surface wear.
• 200 hard outer sleeves (3"×4") lock in card shape and block bending.
• Clear, acid-free materials minimize yellowing and maintain visibility.
• Easy insertion and removal for grading, display, or play.

Will these sleeves fit standard baseball and trading cards?

Yes — the hard sleeves measure 3"×4" externally and the soft sleeves are sized to accept standard 2.5"–2.75" wide trading cards with a safe margin for sliding. The combined dimensions provide a secure fit without tightly compressing the card, reducing edge wear during handling.

• Designed for standard 2.5"×3.5" cards (baseball, basketball, Pokémon, etc.).
• Soft sleeves accommodate slight size variations from different print runs.
• Rigid shell prevents warping when stacked or boxed.
• Works with common storage accessories like top-loaders and binders.

What materials are used and how do they affect durability and clarity?

PJU uses acid-free, anti-scratch plastics for both layers to maintain long-term clarity and card condition. The hard sleeve is sturdy enough to resist creases and impacts, while the inner sleeve offers a smooth surface that reduces friction and fingerprint transfer.

• Acid-free plastic reduces risk of long-term discoloration.
• Anti-scratch surfaces preserve card artwork and gloss.
• Clear transparency ensures cards are viewable without removal.
• Durable construction supports repeated use and shipping protection.

How should I use these sleeves for storage, display, or shipping?

Slide each card into a soft sleeve first, then place that sleeved card into a hard sleeve for full protection. For display, keep cards in the hard sleeve and place into stands or binders; for shipping, combine sleeves with top-loaders or padded mailers for added security.

• Insert card into soft sleeve to prevent surface scratches.
• Place sleeved card into hard sleeve to maintain flatness.
• Stack vertically or box in quantities to limit pressure on corners.
• Add bubble wrap or top-loaders when mailing valuable cards.

Who is this pack best for? Collectors, hobbyists, sellers, and tournament players who need cost-effective, reliable protection for large numbers of standard-size cards will find this 400-count set ideal. The combination of soft inner sleeves and hard outer shells suits everyday handling, long-term storage, and transport—making it a practical choice for anyone who wants to preserve card condition while keeping pieces visible for display or sale.
