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

4. For carrying rather than posting
BCW Graded Locking Case
BCW · Taking slabs to a show
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.
