I love my new Linkyp Liquid chalk markers. They are so bright and vibrant. I can write on anything with then plastic, glass, mirrors, metal and glossy boards. They are so easy to wipe it off also. They are just so fun . We use them to write on the car windows to cheer on our teams. Then the next day it just wiped right off. We also use them to write on our windows at home for different holidays. It wipes right off as well. I am just in love with these chalk markers.
