Koogel4x6 Index Cards Blank, 180 Count, 9 Assorted Neon Color, Flash Cards for Studying School Supplies, Office

These always come in handy. The price is reasonable with the quality of the cards.

Cards are just the size I was looking for, and I like the colors. I plan to use different colors for my different to-do list each day. They're just not as thick/sturdy as I expected. But I wouldn't call them flimsy.

This is more like smooth construction paper, not heavy card stock! Don’t waste your money

Nice colors but not the usual index card thickness. Misleading.

Not really cardstock, more like heavy paper. They would never survive in the mail.

These are listed as flash cards or index cards, but they are just paper cut to that size. Colors are bright, but this is NOT thick enough to be considered a card - it's basic paper thickness. I'm going to double or triple them up to try to get card thickness and tape them together, but overall this is a waste.

These are basically colored paper sized 4" x 6". They are fine if you aren't actually looking for index card sturdiness. I am using them for a work project where they will be laminated, so it's not a big deal. But, if you're not laminating them I would go elsewhere for index cards.

I bought these for recipe cards. They are beautifully packaged, love the colors. Opened the package up and pulled out the cards...and they're flimsy paper, not cardstock. I could see using these as ... origami? tiny letters? some sort of papercraft where you needed brightly colored paper (not cardstock). I'm really disappointed.
