Quick answer
Choose a Warhammer 40k codex folio based on which book or datasheet you need to protect. The Universal Codex Book Folio fits any codex or core book, the Necrons Codex Folio adds faction-specific art, and the T'au Empire Datasheet Folio is designed for organizing loose datasheets and index cards.
What a codex folio does for your game night
A codex folio is more than a cover—it's a padded, portable case that keeps your Warhammer 40,000 rulebook or datasheets safe from spills, bends, and wear during travel and play. Each folio uses a textured leatherette exterior and an easy-load back pocket so you can slide your book in quickly without fuss.
The key difference between models is the interior layout and the faction theme. Some are built for a single codex or core book, while the T'au Empire version has multiple pockets designed specifically for 10th Edition datasheets and index cards.
Faction art vs. universal design
If you want your storage to reflect your army, the Necrons and T'au Empire folios feature foil faction symbols and warriors. The Universal Codex Book Folio uses a grimdark quote and spot UV pattern, making it suitable for any faction or for collectors who prefer a more neutral look.
All three use metal emblem accents or foil details, so the choice comes down to personal preference and whether you want your folio to match a specific army.
How to choose the right codex folio
- Do you need to carry a codex or core book?: If yes, pick the Universal Codex Book Folio or the Necrons Codex Folio. Both have a single back cover pocket that fits the current Warhammer 40,000 Codex or Core Book. Measure your book's thickness against the folio pocket; the catalog does not specify a maximum page count, so a standard codex should fit comfortably.
- Do you want faction-specific artwork?: If you want your storage to match your army, the Necrons Codex Folio has foil Necrons symbols and a spot UV warrior. If you prefer a more neutral look, the Universal Codex Book Folio uses a grimdark quote and abstract faction pattern.
- Do you mainly use datasheets and index cards?: If you rarely bring a full codex and instead rely on datasheets for unit stats, the T’au Empire Datasheet and Index Card Folio is the right choice. It has ten double-sided, 4-pocket pages sized for 10th Edition Datasheets plus extra index card pockets. This folio does not hold a codex book—choose it only if datasheets are your primary reference material.
