How to Pack & Ship Single Cards Without Getting Burned

One bad review for bent corners, dented grading slabs, or water-damaged mail can ruin a seller reputation you spent months building. Packing cards right is a skill every collector needs.

1. The Foolproof Armor Stack

• Penny Sleeves: Always slide your raw cards in top-down. This keeps dust and moisture from creeping into the top edge over time.
• Card Saver I (Semi-Rigids) & Toploaders: The gold standard for high-end singles and sending cards off to grading (like One Piece Manga rares or Gundam SP chase hits).
• Resealable Team Bags: Waterproofs your semi-rigid or toploader, keeping the card securely centered and safe from rain or postal sorting machine mishaps.
• Rigid Mailers & Bubble Mailers: Never ship a valuable card in a plain envelope without sturdy cardboard stiffeners taped securely on both sides.

2. Packing Graded Slabs (PSA, CGC, TAG)

Slabs need extra love so the plastic doesn't crack in transit. Wrap the slab in multiple layers of bubble wrap, secure it with painter's tape (never put sticky packing tape directly on a slab), and sandwich it between two thick pieces of cardboard inside a sturdy mailer or small box.
