Manga Slab Protector

Graded manga is its own world: different slab dimensions, different shelving habits, different way collectors live with their books. KEYGUARD's manga slab protector is a premium TPU bumper sized specifically for graded manga slabs, wrapping the most exposed edges in shock absorbing thermoplastic polyurethane without hiding the book or the label.

Why graded manga needs a protector built for manga

Manga slabs aren't the same outline as a standard comic slab. A bumper molded for a CGC comic holder fits loose or not at all on a graded manga volume, and a loose protector is worse than none: it shifts, scuffs, and gives false confidence.

KEYGUARD's manga bumper is sized around the manga slab profile itself, in both manga slab sizes, so the fit is the same snap-on, stay-put experience comic collectors already get.

Built for how manga collections actually live

Manga collections run deep. Dozens of volumes, shelved spine-out in tight rows, pulled and reshelved constantly. That sliding contact is exactly where slab edges pick up scuffs and corner chips. A TPU manga slab protector takes that contact on the bumper instead of the plastic.

For wall display, the same collector workflow applies: protect once, display without removing anything.

Molded TPU, not a 3D print

Most manga slab protectors on the market are one-off 3D prints in brittle PLA. They show layer lines, yellow in sunlight, and crack at the corner they were meant to defend. KEYGUARD is injection molded TPU, the same material family used in flagship phone cases: it flexes on impact, returns to shape, and finishes matte and seamless.

Two sizes, one standard

Graded manga comes in more than one slab size, so the KEYGUARD manga bumper does too. Both sizes are $12.99, with the same material, the same matte finish, and the same edge-wrapping profile that leaves the book and label fully visible.

Frequently asked questions

What is a manga slab protector?
A manga slab protector is a bumper, usually TPU, that wraps the outer edge of a graded manga slab. It is designed to help protect the slab from edge chips, scuffs, and direct impact during handling, shelving, and display.
Does KEYGUARD fit graded manga slabs?
Yes. The KEYGUARD manga bumper is sized specifically for graded manga slabs and comes in both manga slab sizes, rather than reusing a standard comic slab profile.
Will it fit my CGC graded manga?
The manga bumper is built around the graded manga slab outline used by the major grading companies. Due to normal manufacturing tolerances, fit may vary slightly on older or reholdered slabs.
Does the protector hide the book or label?
No. It wraps only the outer edge of the slab, leaving the cover art and grading label fully visible.
How much is the KEYGUARD manga slab protector?
The manga bumper is $12.99 in either size, with a limit of 10 per order. Shipping is a flat $9.99 in the USA, $25 to Canada, $50 to Europe and Dubai, and $75 everywhere else.
Does a manga slab protector guarantee my slab won't be damaged?
No accessory can. KEYGUARD is designed to help reduce everyday wear and direct impact exposure but cannot guarantee prevention of damage under all conditions.
