I recently picked up this pack of 100 semi-rigid card holders and 100 soft sleeves for my trading cards that I sell on eBay, they've been great for keeping everything safe during storage and shipping. As a collector of Pokémon and sports cards, I appreciate how these provide double protection— the semi-rigid holders prevent excessive bending , while the soft sleeves guard against scratches and fingerprints. They're perfect for submissions as well, and the materials feel high-quality and durable, much better than some cheaper alternatives I've tried. I haven't had any issues with shipping: I ship my loose cards in a sleeve inside this semi ridged card holder and 400 gsm ridged envelope and haven't had any issues with damages or returns. The universal sizing fits standard cards snugly without any issues, and they're acid-free, which gives me peace of mind for long-term storage. Overall, this set offers excellent value, especially compared to pricier brands, and has made organizing my collection a lot easier. Pros -Excellent Protection: Double-layer design keeps cards safe from bends, scratches, fading, and corner damage—ideal for grading submissions. - High-Quality Materials: Acid-free, anti-scratch PVC that's sturdy and durable, ensuring cards stay in pristine condition. - Universal Fit: Works well with a variety of cards, including Pokémon, baseball, football, MTG, and Yugioh; sleeves are slightly wider for easier insertion. - Great Value: Affordable price for 100 holders and 100 sleeves, with better quality than expected for the cost. - Clear and Versatile: Ultra-clear view for displaying cards, and versatile for storage, shipping, or grading. - Secure Hold: Cards stay in place without shifting, providing reliable security. Cons - Insertion Can Be Tricky: Some cards are a bit hard to slide in at first, though they loosen up with use. - Not Fully Rigid: They're semi-rigid, which makes them flexible but slightly flimsy compared to fully rigid options, potentially less ideal for very heavy-duty needs. So consider your needs before making a purchase.
