Set of 3 DGK "3 in 1" Gray White Black 18% White Balance and Exposure Control Tools

Great price. Looks like they'll work well. I plan on cutting one up for my camera back to take around with me. I like that they have white and black so you can check your exposure too that helps more than you know! Now everything is exposed well

Arrived bent with bag torn. Still usable, but doesn't look great.

The material itself isn't all that good but you get what you paid for. Not particularly something you'll keep for a long time but it's still developed decently.

I use this for setting exposure as well as fine-tuning white balance. Three eye-droppers on the 3 colors in Aperture 3, and white or gray for white balancing, and my color correction is practically finished. You can't get more simple than that (using RAW). It does what it is supposed to do.
