Review on Chalkboards Non Toxic Dustless Erasable Reversible by Nicole Mcleod

I liked her at first. They look good, they are bright and it makes my room very cute. I used them on my board that I painted on my door with an Oleum rust stain. When I tried to erase after a few days it erased the fin but as you can see in the photos it left material of what I had previously written. It's good I won't be changing the board any time soon, but if I do I'll have to repaint it. I am very upset and will be sending it back. DO NOT BUY IF YOU PLAN TO WRITE ON THE CHART WITH PAINT - I'm not familiar with the normal chart. I am very upset with this product. I would give 0 stars if I could. Update: My surface was porous. The product said non-porous. just know It's my fault for not reading carefully.
