Incredimarkers, in exchange for honest review from Tomoson. The markers are sold by Ander Blake. I received a set of 8 colors: yellow, white, pink, orange, blue, green, red, and purple.
I used the markers to write to do lists on my desk. I also used them to label my bins to identify the contents.
To use the markers, you shake the markers first. Then, press the tip down until the liquid chalk, reaches the end, and decorate away. Maybe you want to label something instead.
I recommend using a scratch sheet of paper or an empty area of your desk to press the tip on, just in case too much comes out.
You can purchase the markers on Amazon, using the link above. The markers are prime-eligible.
