In exchange for my honest unbiased opinion I received a set of Colore Art 8 count chalk markers. They are brightly colored and work really well. They can be used on many surfaces however not on regular chalkboards. they are great on car windows or even house windows. Be creative without the worry of destroying things are screwing your design up. They are both chisel tipped and round tipped. Very easy to use and cleanup. they come in a nice silicone holder that is vibrantly bright colored also. My holder is bright neon yellow. I just love these chalk markers. Surprisingly I thought they were going to be horrible and I was leery on trying them but I found out different upon getting them and found I really like and enjoy them for lots of things.
