2,000 SUPER THICK index cards 3x5 17pt - Heavyweight archival

Our review of these 2,000 SUPER THICK index cards finds them best suited for students, teachers, and creatives who need heft and durability in a small card format; the single biggest reason to buy is the cardstock weight: at 130lb 17pt (0.017 in) these cards feel substantially thicker than typical store brands and stand up to repeated handling without bend or bleed. The cards are blank and un-ruled, with a bright white uncoated surface that soaks in gel pens, markers, watercolor, and inkjet inks, and they are made in the USA from archival, acid-free, FSC certified stock.

Key Features

• 130lb 17pt thickness: Provides rigid, postcard-like durability so flashcards and study sets resist bending and last through heavy use.
• 98 bright white uncoated surface: Absorbs ink and watercolor nicely so writing and color stay vivid without excessive smearing on the surface.
• USPS acceptable thickness: Meets thickness guidelines for postcards when mailed, which is useful for DIY mailers and craft projects.
• Archival and acid-free: Elemental chlorine free and archival quality mean notes, art, and records will stay stable over time without yellowing.
• Made in USA and FSC certified: Manufactured to identity and chain-of-custody standards favored by buyers who care about origin and responsible sourcing.
• Bulk pack of 2,000: Large quantity offers good value for classrooms, clubs, or heavy users who prefer to buy in one shipment.

Who It's For

These cards are ideal for students making durable flashcards, teachers preparing reusable study aids, and artists testing inks or small watercolors; the 17pt weight keeps cards flat in backpacks and on desks. They are also a good fit for small business owners who need sturdy cards for mailing or product tags where thickness matters.

Those who need printable cards for common home inkjet printers should note that 17pt can be too thick for many desktop printers; if you plan to run these through a printer, request a free sample first or consider the 14pt option. If you want ruled or pre-lined index cards, these blank un-ruled cards may not be the right choice.

Pros & Cons

Pros
