Amazon Basics Ruled Index Flash Cards for Studying and Note Taking, Assorted Neon Colored, 3x5 Inch, 300-Count

Perfect for studying and the thickness of each index card is very good quality. I like how It came with multiple colors so I can separate my cards by subject and it’s very helpful.

I used these index cards throughout my 10-week dental assisting school and they worked perfectly. The lines helped keep my writing neat and the cards are thick enough that marker or pen doesn’t bleed through. I used them for quick notes, flashcards and study guides. They’re simple but super helpful and way cheaper than other brands. If you’re in school or just like writing things out by hand, these are definitely worth it!

Bought for recipe cards. They are very thin. Doubtful they will hold up for lots of use.

Great value and lots of cards. Can't complain.

Good sturdy cardstock and colors are very Brite. Some i have bought are like paper, these are awesome and are thick. Have 4 bulk packs of these on Subscription every month.

These are indeed neon-bright index cards. They work as they should. I've been using these well over a year, and they hold up to light handling. However, they are not as heavyweight as I prefer in an index card. There is nothing wrong with these cards, and they may meet your needs (I made do with them for a longtime), especially when price is taken into account. However, I've decided I need a heavier weight card. If you want a truly heavyweight colored index card that is sturdier and more durable, I found the 80-lb. cardstock ones by Chell: https://www.amazon.com/gp/product/B0DCZPG3G1/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1. I have no relationship to that brand or seller, but thought this info might help someone else, too. While the Chell cards aren't neon, I find their "pastels" to be quite vibrant. The Amazon neon cards weigh 14.4 ounces for 300 cards, or 4.8 ounces per 100. The Chell weigh 7.4 ounces per 100, so you get a card that's 54% heavier (so much thicker, too). That's quite a difference, and I can definitely feel the difference.Bottom line:Amazon neon cards: Brighter, decent, definitely not heavyweight, yet definitely a lower cost per card (at most 2.3 cents per card late 1/2025, depending on if on sale or not).Chell cards: Heavy weight (significantly heavier), colors vibrant, holding up better during my use. While they do cost more, can save money by buying pack of 200, and the cost differential is partly due to the cost for the extra material in the cards. When buying 200 at a time: essentially 4 cents a card (late 1/2025).

These cards have multiple good uses--shopping lists, flash cards, and so on, but one I use them for I doubt most would think of. When I'm writing a 4x6 blank card to someone and the glossy back will not take additional writing from my pen, I rubber cement the blank side of this face up on the back of the 4x6 greeting card, let it set, then write the rest of the text that I want to say to the recipient. When the rubber cement is dry, I rub off the excess and nobody is the wiser that I've added an additional card to the back of the more formal card to make additional writing possible.

I love these index cards, especially the 4X6. The size is perfect for notes I need to make here and there, like writing down something I remembered that I’m going to forget right away. I keep these cards in each room with a pen. The colors are vibrant which is not what you find in the local stores.
