I received these markers for review from Chalkola. I definitely give them 5 out of 5 stars. The colors are bright and vibrant. The markers are easy to use and clean up nicely off chalkboard, glass, and mirrors with just a wet cloth.
Even my children were excited about using them as you can see. They are non toxic and do not have a strong smell. They are also acid free.
I did a technique comparison below and the markers worked for all of them but I thought the blending was the most fun. I highly recommend these.
