## Overview

These 100 SUPER THICK index cards are crafted from 100lb, 14pt card stock, measuring 3" x 5". With a smooth, uncoated surface, they are perfect for various writing instruments and are made in the USA. Archival quality and acid-free, these cards are designed to last while being environmentally friendly and USPS approved for postcard use.

## 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.

### ⭐⭐⭐⭐ 







  
  
    A Recommendable Product
  

*by M***L on Reviewed in the United States on April 14, 2023*

I got this product to use as flashcards for learning a language. Most index cards, in my experience, are too thin and see-through for my liking, especially the blank ones. I wanted cards that were thick and didn't bleed through when using a sharpie.I purchased the 14pt, 100lb, cards. These are pleasingly thick. However, they can bleed through if you're heavy handed or write slowly when using a sharpie or other felt tip pen. I decided to use a bold gel pen and I'm pleased enough with the results.These cards are also see through if held up to a light source. That's not a dealbreaker for me, but it's something to consider depending on your needs or uses.Overall I'm pleased with these cards and recommend them.

    I wanted non-bleed quality index cards.
  

*by E***H on Reviewed in the United States on April 16, 2023*

They are well-made. Get them if you care about good, non-bleed index cards.

    What a relief to find these cards!
  

*by K***E on Reviewed in the United States on February 11, 2023*

I really appreciate Chris making these thick index cards. As someone in grad school who also has a high school student, these are so helpful. The cards you can buy in the store are so flimsy. These cards don't bend easily and are long-lasting. Most importantly, you can't see through them. I always use thick, dark pens. What's the use of a flashcard if you can see the answer? No worries with these. I know you can make flashcards via many apps and websites, but handwriting the cards helps me learn the material. Chris, the creator, is so nice and helpful. The cards arrived SO quickly and in great shape. Thank you.
