Core is the foundation of L4YR — our entry-level slab guard built to give your collection everyday protection with style. Made in the USA and 3D-printed by hand from durable PLA, each guard is crafted with care to deliver a snug fit you can trust.
Available in a range of consistent colors, Core is designed to accentuate and complement the card itself, adding just enough personality without overshadowing the slab. Whether your cards live on a shelf, travel with you to shows, or get passed around at a trade, Core provides the protection you need with a clean, collector-focused design.
This is the guard that started it all: simple, reliable, and made for collectors who want their slabs to look as good as the cards inside them.
