I bought both to compare. If you want index cards that feel thick like the ones of 20+ years ago, get these Amazon ones. They are a heavier card stock and are more sturdy for using to flip back and forth if you’re quizzing yourself or writing on both sides and don’t want to see bleed-through writing shadows. Also the lines on these are printed slightly darker, in more of a navy blue ink. I believe they’re worth the difference in cost. Amazon is $0.0313 per card. Olivo are $0.03495 per card. For 300 cards, it’s the equivalent of $10.49 for lesser quality Olivo versus $9.39 for Amazon; or $1.10 less for the cards you know you’d rather have anyway! Happy note taking!

Lined Perfection: The Poet's Grid The subtle ruling on these cards is an unsung masterpiece. Neither too bold nor too faint, the lines guide your words with the grace of a ballet instructor—firm but never intrusive. Whether you're drafting epic to-do lists, sketching the outline of your next novel, or jotting down a recipe destined for greatness, these cards are your unswerving confidants. Heavyweight Champions: Sturdy as Stone Unlike lesser cards that crumple at the mere sight of a backpack or a breezy day, these index cards stand tall. I have subjected them to the harshest conditions—pockets, purses, and even the treacherous bottom of my desk drawer—and they emerge victorious every time, unbent and unbowed. 100 Reasons to Smile With 100 cards in each pack, the possibilities are endless.

I get these over and over again! I like how they are blank on one side and lined on the other. I also like how high quality of paper they are and you can use a pen and it will not bleed through. Easy to store and can fit in books, pockets, literally anywhere!

Decent quality, better than several big name brands as the lines are even on every index card. The most smooth index cards that doesn't clog pens, each index card absorbs ballpoint ink just as great as gel inks. Handles high-lighters and markers, doesn't lose the shape from that extra ink.

Card quality is slightly lower and thicker than other cards I have used, but overall is great for the price! No complaints.

Great price and quantity. Enough that it might just get us through college! The little packs went too fast and always needing more. So came to Amazon and bought this bundle for less money than I would have paid for individual packs.

These are probably the most inexpensive index cards you can find nowadays. One side is lined while the other in blank, as described. Color matched the description, and the card stock is pretty strong.

Perfecto

Las fichas son extremadamente delgadas. No las recomiendo.
