100 Black Rigid Mailers 7" x 4.35" Trading Card Shipping Envelopes for Collectors

PRECISION FIT FOR TRADING CARDS — DESIGNED FOR STANDARD PROTECTORS Designed specifically for trading card sellers and collectors. Each 7" x 4.35" envelope accommodates a standard card housed in semi-rigid CS-1 sleeves or standard rigid card protectors, with room to spare for a 4" x 6" shipping label. No more trimming, folding, or forcing your cards into the wrong size mailer — just a clean, professional fit every time.
Crafted from premium lightweight cardstock weighing approximately 0.4 oz per mailer — rigid enough to shield your cards from bends and corner dings during transit, yet thin and flexible enough to comfortably qualify for USPS First-Class Mail and eBay Standard Envelope rates. At just under 0.25 inches thick when loaded, your shipment stays well within automated sorting machine limits — no non-machinable surcharges, no returned mail, no headaches.
SELF-ADHESIVE PEEL & SEAL — NO MOISTURE, NO MESS, NO HASSLE Each mailer features a strong self-sealing adhesive strip — just peel the liner, fold, and press to seal. No licking, no water, no tape required. The flat-glued side seams ensure smooth passage through USPS sorting machines, reducing the risk of jams, tears, or returns. When you're shipping dozens of orders a day, this speed and reliability makes all the difference.
PROFESSIONAL PRESENTATION — MAKE EVERY SHIPMENT COUNT Whether you choose crisp white or sleek black, these mailers give your shipments a clean, polished look that tells buyers you mean business. Pair them with your preferred card protectors for a complete packaging solution that enhances your seller reputation, encourages positive feedback, and keeps customers coming back for your next break or auction win.
