I just started a language class and wanted something other than 3" x 5" cards to use as flash cards. Especially since I have had trouble finding any 3" x 5" "cards" that aren't more like paper. What happened to the serious index cards that were stiff and didn't bend like wet noodles?Anyway, I wanted something with colors and a little smaller than index cards and decided to give these a go.I like them. They are a nice size. They do not feel flimsy. I would have liked them to be a touch larger, but not a deal breaker. Nice colors. Rings seem to be good enough quality.My only nitpick is that I only received 3 rings. With the huge number of cards you get, I'm going to need more rings anyway. But it would have been nice to get all 5.Happy with these.Could come with more than just the five ring but overall a great buy! Does the trick and the perfect size. Color coated for different subjects as well. Can’t beat great pick by me and I can happily live with this one. I’m telling all my study buddies!I liked the size and that, the various colors, and that permanent marker did not show through.My cards didn't come glossy. Ink pens work fine. Im using the pilot g2 07 and there is not smearing, immediately after writingThey are perfect colors, size, thickness and have the holes and rings included.love these for making small flash cards. they have been super helpful in learning sight words.I teach a child who is blind and these are great to braille flash cards on! I love themGreat product, I just wish they would send more rings.
