2,500 SUPER THICK index cards 3x5 14pt - Durable archival bulk pack

Our review of these 2,500 SUPER THICK index cards finds them best for students, teachers, and anyone who needs durable, archival flashcards or note cards that stand up to heavy handling. The single biggest reason to buy is the cardstock: at 14pt (0.014 in) and 100lb weight, these cards are noticeably thicker than typical store brands and resist marker bleed-through while still taking ink and watercolor well. For people who want bright white, uncoated cards that feel substantial and last, this pack delivers reliable quality in a bulk, value-oriented format.

Key Features

• 14pt 100lb card stock: Provides a thick, rigid surface that holds up in backpacks and on busy desks without flopping or tearing.
• Uncoated smooth finish: Absorbs gel pens, ballpoint, markers and inkjet inks cleanly while minimizing bleed-through for legible notes and flashcards.
• 98 bright white: Offers high contrast for markers, highlighters and printed text so handwriting and prints read clearly.
• Archival and acid-free: Ensures notes and study materials resist yellowing over time, suitable for long-term storage of important cards.
• USPS postcard compliant thickness: Thick enough to feel premium but still within postcard mailing rules for those who need to mail cards.
• Made in USA: Manufactured domestically, which may matter for quality control and sourcing preferences.

Who It's For

These index cards are ideal for students building durable flashcards, teachers preparing classroom materials, and crafters or artists who want a sturdy uncoated surface for markers, watercolor washes, or ink. The bulk pack of 2,500 is a good fit for heavy users who prefer not to reorder frequently and for printing batches of study cards.

People who need ultra-thick board that will run through every home printer should be cautious: while the 14pt cards are more printer-friendly than the 17pt or 25pt options, some printers may still struggle. Casual users who only need thin, cheap cards may prefer a lighter, less expensive alternative.
