100 SUPER THICK index cards / 3"x5" / 14pt (0.014") 100lb / blank un-ruled/archival acid-free

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.

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

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.

I use these cards as dividers for a collection of spare diamond painting drills. I love these cards because they are heavyweight, sturdy, and work perfectly as stiff dividers for separating heavy zip-lock plastic baggies full of drills. They make sorting through the bags effortless and they stand up straight in the storage container. The seller mailed the cards very carefully. They were wrapped tight in a sturdy cardboard box along with a clear receipt and a handwritten note to please contact if there happened to be any problems. I would not hesitate to order from this company again. They are top-notch!

These are great, I am a reoccurring purchaser.

Item came in quicker than expected. Exactly as advertised and packaged nice and tight so not to be damaged during shipping.

The 3x5 cards you can buy at Office Max are made from thin stock, cut to size.These cards are the real thing. Thick and heavy, they are perfectly sized and will be very durable. They feed through my Epson printer just fine, and the print quality is excellent with no bleeding toner. The order processing and delivery were fast and on time.Just a straight up business deal of a quality product with quality service. Can't ask for anything better.

I'm happy with this product. It's a heavier weight cardstock, just what I was looking for to use for making miniature collage art.
