The stack is penny, toploader, team bag, cardboard. Anything sticky stays off the card.

Most postal damage is not a dramatic crush. It is a corner tapping the inside of a loader, a card sliding out into the envelope, or tape glued to a sleeve. Build the parcel so the card cannot move and so nothing adhesive can reach it.
The stack
Clear penny sleeve. This is the soft layer.
Toploader that fits without force. 35pt for a normal sleeved card, thicker if you already double-sleeved it.
The sleeve opening toward the bottom of the loader, so the card is not working its way out of the open end.
A resealable team bag over the loader.
If you tape, tape the bag. Painter’s tape. Not across the card, not on the penny sleeve.
Sandwich the loader between two pieces of cardboard bigger than it is, or use a small box. A bubble mailer on its own still bends.
Several cards: each in its own loader, bagged, and packed so they cannot slide into each other. A rubber band around a stack of toploaders is still a bad idea. Write do-not-bend on the parcel in marker as well as using a sticker — stickers come off.

Ultra PRO penny sleeves
Ultra PRO
Soft, cheap, and the correct first layer inside a toploader or card saver.
Buy them by the hundred for bulk storage and for anything going into rigid plastic. They are not for shuffling — they stick, cloud, and slide apart. Check the pack says polypropylene if you can.
Fits
Standard size
Use
Bulk binding, toploaders, grading submissions, posting a card.
Rigid 3×4 holders. The everyday case for a penny-sleeved card.
Always penny-sleeve first so the card does not scrape the rigid plastic. 35pt fits a normal sleeved card. If you have to push, stop and go up a size — forcing chips corners.
A thicker rigid holder for double-sleeved cards and chunky holos.
A double-sleeved card, or a stack of a penny plus a thick textured card, often bows a 35pt. 75pt, 100pt and up exist for relics and patches — match the stack, do not compress it.
