The short answer

Sleeve it, immobilize it between cardboard, box it so nothing moves, insure it

A graded case is rigid, which makes people complacent. Slabs crack at the corners when they are free to move inside a package, and a cracked case on arrival is a dispute whatever the grade says. Immobilization is the entire job.

The failure mode for a graded card in the post is specific and predictable: the case takes a corner impact while it has room to move, and it cracks. Every step below exists to stop the slab moving.

Packing one slab

  1. Sleeve the slab, which prevents surface scuffing even if everything else goes right.
  2. Sandwich it between two pieces of rigid cardboard cut larger than the slab, so the corners are not the first thing anything touches.
  3. Tape the sandwich closed around the edges, never across the slab face.
  4. Wrap the sandwich in bubble wrap, paying attention to the corners.
  5. Put it in a box with no room to move, filling voids so the package can be shaken without anything shifting.
  6. Ship tracked and insured, with a signature on delivery where offered.

1. Step one

GradedGuard PSA Slab Sleeves

GradedGuard · Scratch protection on a PSA slab

GNo product photo

A sleeve cut specifically to PSA slab dimensions. The slab protects the card; nothing protects the slab, and a scratched case is what drops a slab's resale appeal.

Why it takes this slot: A sleeve prevents the scuffing that happens in transit even when the case survives.

Fits
PSA slabs
Purpose
Protects the case from scratches, scuffs and handling wear
Format
Slip-on sleeve, sold in multipacks

What it does well

  • Precision fit means the slab does not slide inside the sleeve
  • Keeps the case presentable through repeated handling and shipping
  • Cheap relative to the slab it protects

Where it falls short

  • PSA-specific — confirm the fit before buying for BGS, CGC or SGC
  • A sleeve does not protect against impact

2. For high-value shipments

X PRO PSA Slab Protector

X PRO · Impact protection on a traveling slab

XPNo product photo

A TPU bumper rather than a sleeve. If slabs travel with you to shows, a bumper takes the corner hit that cracks a case.

Why it takes this slot: A TPU bumper absorbs the corner impact that cracks cases, which is the specific failure mode here.

Fits
PSA slabs
Material
TPU bumper guard
Pack size
12-pack

What it does well

  • Absorbs corner impact, which sleeves do not
  • Sold in counts that cover a show box

Where it falls short

  • Adds bulk, so fewer slabs per case
  • Color finishes are a matter of taste

3. For shipping several

BCW Graded Card Storage Box

BCW · Storing slabs you are not displaying

BNo product photo

A slotted cardboard box sized for slabs rather than raw cards. Most of a graded collection should live here, not on a wall.

Why it takes this slot: A slotted box keeps multiple slabs separated and square inside the outer carton.

Capacity
Roughly 30 graded slabs per the manufacturer
Fits
PSA, BGS, SGC, CSG and HGA slabs, plus BCW 4-screw holders
Material
Corrugated cardboard with slots

What it does well

  • Slots stop slab-on-slab scuffing
  • Takes mixed grading companies and screwdowns together
  • The cheapest way to store slabs properly

Where it falls short

  • Cardboard offers no moisture or impact protection
  • Thicker BGS cases eat the stated capacity

BCW Graded Locking Case

BCW · Taking slabs to a show

BNo product photo

A three-row hard case with dense foam, built with Zion Cases. If slabs leave the house, this is the format that gets them back intact.

Why it takes this slot: If you are taking slabs somewhere yourself, foam and a hard shell beats any packing.

Capacity
Three rows of graded slabs
Interior
Dense foam base with soft foam lid lining
Closure
Locking hard case

What it does well

  • Foam plus a hard shell is real transport protection
  • Locks, which matters on a show table

Where it falls short

  • Heavy
  • Costs many times a cardboard slab box

Shipping several at once

Do not stack slabs directly against each other and band them. Use a slotted slab box so each case is separated, then treat the box as the inner package: wrap it, void-fill the outer carton, and ship that. The slots do the immobilizing work that bubble wrap does badly between flat rigid objects.

What goes wrong

  • A padded envelope with no rigid protection. The most common way slabs arrive cracked.
  • Tape across the case face, which marks it when removed.
  • A box with void space. Movement is the whole problem.
  • No insurance, which turns a damaged shipment into a total loss.
  • No photographs before sealing, which turns a dispute into your word against theirs.

If you are shipping raw cards to a grader rather than slabs to a buyer, the requirements are different — see how to ship cards to PSA.

Common questions

How do I ship a graded card safely?
Sleeve it, sandwich it between rigid cardboard larger than the slab, wrap it, and box it so nothing can move. Ship tracked and insured, and photograph everything before sealing.
Can I ship a slab in a bubble mailer?
Not safely on its own. Slabs crack at the corners under impact, and a mailer offers no rigid protection. Use a box with the slab immobilized inside.
How do I ship multiple graded cards?
Put them in a slotted slab box so each case is separated, then treat that box as the inner package inside a void-filled carton.
Should I insure a graded card shipment?
Yes, to the card's value, and keep the tracking and your pre-shipping photographs. A cracked case on arrival is a dispute you want evidence for.
