1,000 SUPER THICK index cards 3x5 17pt - Heavy Duty Flashcards

In this review the focus is on whether Norstrom Dumati's 1,000 SUPER THICK index cards are worth buying for students, teachers, artists, and crafters who need a heavy, archival blank card. The bottom line: these 3 in x 5 in cards use 130lb, 17pt stock that feels substantially thicker than typical store cards, and the single biggest reason to buy is durability - they survive backpacks, heavy handling, and ink without bleed through. For anyone who needs rigid, archival blank cards for flashcards, postcards, or mixed-media notes, these cards deliver a noticeably premium feel.

Key Features

• 130lb 17pt thickness: The substantial weight gives each card a rigid surface that holds up to handling and prevents curling when stored.
• 98 bright white uncoated surface: The smooth, uncoated finish soaks in gel pens, markers, and inkjet inks without the gloss that repels writing.
• Archival acid-free stock: Elemental chlorine free and acid-free paper preserves writing and artwork long term without yellowing.
• USPS approved postcard thickness: Thick enough to meet postcard rules, so cards can double as mailed notes when needed.
• Made in USA: Domestic production means consistent quality control and card stock that matches the listed specs.

Who It's For

These cards are ideal for students making durable flashcards, educators building reusable sets, artists experimenting with small watercolors or markers, and small businesses producing thick postcards or product tags. The sturdy 17pt stock particularly benefits users who need tactile, long-lasting cards rather than flimsy paper.

Those who need index cards that run through most desktop printers should be cautious: the 17pt thickness is thicker than many printers will accept. If you plan to print directly at home, request the free sample to confirm compatibility or consider the thinner 14pt option mentioned by the brand.

Pros & Cons
