Most of the colors worked except for white and yellow. The white wouldn't work at all (I let it dry). And depending on if the marker tip touched any place that was already dry (writing from the markers), the marker in use would stop working. The idea is fantastic, the execution is faulty.
I would recommend this to a friend!

These look good and are easy enough to wash off, a baby wipe and a piece of kitchen roll take it off, even after a week on the window. Unfortunately they don't apply well, instantly drying into an almost invisible thin line of dots, nothing like the picture on the box. I tried going over the lines a few times to build layers or colour in. It works better for some colours like orange but not for green but you definitely couldn't colour in with them. They're a great idea but I haven't found a way to make them work on an ordinary house window.
My husband bought these a while back for our toddler. We use them on the fridge and on the window BUT what we have been using them for lately is for the glass top on our kitchen table! I’m in the process of redoing this table, but I’m glass I kept the glass! This is perfect! Endless fun!
We got these a couple months ago and they are really cool. The effect is fun to watch. We used them once and stuck them in a zip lock and put them away. We went to use them this morning and they exploded or something. All of the markers have some weird white hard powder all over them. Pretty sure they are trash now.
No, I would not recommend this to a friend.
