Koogel 400PCS Index Cards, 4x6 Colored Ruled Index Cards with Rings for Back to School, Flashcards Heavy Note Card with Waterproof Covers for Studying Learning School College Office Supplies, 8 ColorsThe Forest Stewardship Council

Whoever invented these index cards with spiral is a genius! These are a life saver. If you’re like me and are extremely organized, welp, these fall into the category of perfectionism. Not only can you have your index card intact, these will also stay protected from wear off because it has a double sided cover. I can carry these and study at any time. The quality of paper is durable. Card size is standard, and thickness is just right.

I love that they're different colors and with a protective plastic cover. They can be assigned for specific projects/chapters or assignments without getting them mixed up. The plastic cover is great for protecting the cards. And they're easily ripped from the spiral to be used as traditional flash cards. Will definitely be ordering more.

The are perfect for studying and quick notes. You are able to rip the card off if you would like loose flash cards. I like having them all in one place. I would recommend. The cards aren’t so thick. They should be slightly cheaper though.

Absolutely love the style of these! The price was great you get so many different colors as well. They are thick and sturdy! Hold up great for what I need them for love the fronts being waterproof that function is a must for me!

Execelent set of index cards. Fantastic for college stuff. Very colorful.

As noted, colors are good

These are perfect for our notes and whatever we’re doing. Great value for our money. Also the thickness of each was awesome - no bleed through

These are great!! Easy to tear off but strong enough to not fall apart. Very sturdy
