## Overview

These 300 premium 3"x5" index cards feature a hefty 17pt (0.017") thickness—over 150% thicker than standard cards—crafted from bright white, acid-free, archival-quality cardstock. Their uncoated surface perfectly absorbs ink from gel pens, markers, and watercolors without bleed-through. USPS postcard thickness approved and FSC certified, these USA-made cards are designed for professionals who demand durability, eco-consciousness, and flawless performance in note-taking, flashcards, and creative projects.

## Description

These SUPER THICK cards are made from VERY expensive card stock, at least 150% thicker than store bought paper thin brands, always acid-free archival quality, and in bright white uncoated finishes so they can soak in everything you put on them. We have 3 thickness options, 14pt, 17pt, and 25pt (store bought cards are about 7pt). My 14pt cards are how thick index cards used to be in the 90s, and are more affordable. They comply with the USPS requirements for postcard thickness, only some printers can handle them, please request free samples to try in your printer. 17pt is thicker, more expensive, and does not go through printers, 17pt is perfect for thick flashcards, or watercolors. 25pt is an extremely expensive and very thick card stock. 25pt feels like a little slice of wood, it's extreme. If you want to compare thicknesses remember this, if you stack 100 of my 14pt cards they'll measure about 1.4 inches tall. 100 stacked 17pt cards will measure about 1.6"-1.7" inches tall, and 25pt cards will measure 2.5 inches tall when you stack up 100 of them. Now measure 100 of your store bought ones, they're only about 0.7" inches tall.Have you noticed that my competitors almost never mention the actual thickness of their cards? They call them "heavyweight" but they don't put the thickness measurements anywhere. I was the first to start listing heavyweight cards on  (check the dates on my listings) and the first to list them under their true thickness measurement "pt". Permanent marker won't leak through. They're perfect for notes, postcards, printing, painting, artwork, and autographs. You can run them through both Laser Printers and Ink Printers and get wonderful results. They're made in the USA.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Best note cards I've ever used.
*by S***S on March 14, 2025*

REALLY pleased with these cards. Regular note cards tend to tear or bend over time. These will hold up over the long haul. Love it that markers do not bleed through and I enjoy that is has no lines so I can add drawings or diagrams to my notes. These were recommended by an author I follow, and I'm pleased as can be with them. Countless uses - flash cards for my homeschooled grandchildren (will withstand their energy!); study notes for myself; and I absolutely love them for my kitchen remodel templates - holds up enough to draw on with heavy marker, then so much easier to cut than cardboard or wood, easy to tape onto my wood or flooring or tiles to make those odd shaped cuts, and holds up so much better than a regular piece of paper. It also was a great edger while painting the ceiling and baseboards. Truly multi-purpose, and for just note taking - superb.

### ⭐⭐⭐⭐⭐ Accurate lising - High Quality
*by S***G on September 15, 2025*

True to the listing - these are super thick & bright. Quality & service are excellent. Prices are good considering the high quality. Small business - support them.

### ⭐⭐⭐⭐⭐ If you need sturdy, they are more than worth it... (17pt. 3x5)
*by R***H on February 27, 2020*

Like many, I've noticed the way index cards have become little more than cut thick paper, not even basic cardstock weight. Part of the reason is in keeping prices about the same while material costs go up and sales go down for major manufacturer product lines. Not that many still use index cards, but I do, and I'm not a student anymore.This is why some major manufacturers now have a limited "heavy weight" series of products that are still thinner than our old index cards, but heavier than the cheapest things currently available.So having access to truly sturdy, thick cards is appreciated. Granted, these are even thicker than I originally intended/hoped for, but they are becoming an every day go-to. I'm satisfied paying a higher price for quality and durability.If you are still accessing an old library card-catalog, these are even thicker than their oldest, thick cards. The 17pt. sized are about the thickness of the index dividers that were once used. While the seller warns not to use these in printers, if you are a little bit antiquarian, be advised these will generally only feed through larger, desktop typewriters, most portable ones not having a platen of sufficient diameter to feed them through. About the only portables I found that could handle these cards was a Hermes 3000 and some of the more recent electric Smith Coronas. If you intend to type on the cards, I recommend the slightly more expensive but lighter weight 14pt. cards.I also appreciate that the seller is so willing to work to make these available in multiple sizes, AND that they are available as blanks. I notice that the major brand heavy-weight cards are all ruled.Overall, these are clearly more expensive than cheap store brand, but providing a better quality and user experience is worth the extra cost. It's not THAT much more unless one usually only uses 10 cards from a pack, then throws the rest away after they get creased and destroyed from leaving them loose in the bottom of a bag. And you'll be supporting a small business and sending a signal that quality matters.
