Works great on my “chalkboard” calendar. Writes super smooth compared to the previous markers I had and I love these colors super bright and show well on the black.
I've used the purple and red regular markers that you see in the chart. The top 5 columns are from the marker that came with the chart. Not this pack. The regular red marker separates or whatever you want to call it. You can see it on the chart where I tried to use it. The red metallic marker was not very bright. The silver metallic marker seemed to be okay. Maybe some of this is because it's got a black background? Idk but they're good enough. I'm happy with the ones that work!
Overall was not happy because I needed to write in a car for a birthday. Easy to use and works but the tip is way too small to write well on an object like a car window. Because it’s Chaulk, can’t thicken by writing over twice. I would return if I didn’t need to use right then. Also, Metallica which is why I ordered are not large they are minis. So again tip was even smaller. So in the end, didn’t do what I wanted.
