100 SUPER THICK index cards/ 4"x6" / 14pt (0.014") 100lb / blank un-ruled/archival acid-free

Long time Index card user - these are the absolute BEST index cards. I love these for how thick they are.When did store index cards get so thin? I haven't been able to find good index cards though shopping at multiple stores and trying different brands, they all are ridiculously thin and who needs a flashcard that they can see through?These are wonderful for note taking, making lists, and postcards. Nice bright white color and no bleeding through when I write with Sharpies. High quality / value. Sure they are a little more expensive than you will spend at a drug store or office supply store. But you can actually use these, if I want the store-quality cards I can just cut up a piece of printer paper.Don't waste your time and money on inferior index cards. These are wonderful and I will surely buy these again.

These are beautifully made, cut perfectly, and even heavier than the Neenah 110# Solar White card stock I’ve been using for stamping cards for ages. These are bright white, lovely smooth surface, cut exactly, and incredibly thick.Now, instead of cutting my own card bases, I use these—PERFECT!!(My only wish—that we could make a special order with specific sizes. I know many stampers and card makers would LOVE these if they could order specific sizes (like 4.25 x 6.25!!); i of course just ordered the larger cards and cut them down. Now I’m spoiled and I can’t ever go back to anything else I thought was “thick cardstock...”I’ve purchased them in all the sizes offered, and love the 17pt thickness. It is much thicker than Neenah 110lb cardstock, and takes dye inks and copics well. Seriously the best thing out there.Thank you for making such a wonderful product!!Added: This is also the BEST thing to use for making stencils!! The thickness keeps the sharp designs cut out by hand (or an electronic cutter like a Cricut or Silhouette), and don’t get so soggy they fall apart. Seriously impressive!!

High-quality product, just as described. Too thick to use with my LaserJet 4050 printer unfortunately, but not surprising for such thick cardstock!

Unlike the flimsy notecards, lined or unlined, these have heft, perfect for what I needed. Excellent Cust service, timely and responsive, couldn’t ask for more than that!

The thickness has a really lovely feel to it.

I discovered these index cards last year, and IT IS now my ONLY go to for index cards. I primarily use these for flashcards. I needed something thick so when I look at the card (in normal position and lighting), I don’t see the answer on the other side. I use these cards for all my biology classes that require memorization or a lot of picture diagrams. I’m a visual and tactile learner, so creating my own flashcards versus Quizlet works better for me.For identification of body parts, bones, muscle, nerves, etc. (i.e. A&P) flashcards, I use the Thick, unruled, 14pt in the 4 x 6. On one side, I print the image. On the opposite side is the answer. I use Font Color “Black, Text 1, Lighter 50%”. I can’t see through the card in this font. If you’re concerned about how white they are, to me, they look bright white. These cards feel lightweight.For constant review of flashcards (i.e. the physiology stuff, microbiology, etc.), this requires more words, but I needed the cards to be durable to allow me to review the information over and over. I can use these flashcards for my college classes, then for the HESI A2 Exam, and then the NCLEX. So, durability is important. For this, I use the Super Thick, unruled, 17pt in the 4 x 6 and 5 x 8. When you look at the card (in a normal position and lighting), you can’t see through the card. These index cards are very thick and are a bit heavier in weight when compared to the14pt thick cards. Also, even though the package says it’s not for printers, which is true for my Canon MB5420, fortunately, my Canon iX6820 printer accepts it, and it hasn’t jammed yet.I have done A LOT of research and tested many cards from the stores and online. Nothing compares to these cards. I WILL NOT purchase index cards from any place. Look no further, it ends here. These index cards are the BEST!!!

I like the thickness of the cards. Very sturdy. However, they jam in my printer. Maybe not in yours. I will us these for hand-written work.

Great quality cards that I use a permanent fineliner (Sakura .05, .08, Micron) on and it won't bleed to the back. I also paint with watercolors and ink on them. The only time the watercolor starts to show through a bit on the other side is if I use a LOT of water. Otherwise the paint doesn't show through. I've done quick watercolors on hundreds of these for fun and will continue to buy these. Nicely and securely packaged. No bent corners. Arrived ahead of time. Buy them.
