They clean off my blackboard easily using a dab of hand sanitizer on a paper towel. Easy to remove (easier than the rainbow brand of glass pen) with a little glass cleaner and a microfiber cloth.

Worked great decorating car windows. Takes some skill to draw from thin to wide. My only complaint is that two of the markers bleed heavily.

The colors are vibrant and easily seen. Easy to draw a variety of things with varying line thickness. They show up on the windows well, especially the white. Super bright colors and the kids love them!

Worked fantastically. If willing to put in the time can get truly amazing result for amateur. Shake really good 2. Will do more.

Totally bummed. Will be returning. Washing off the car body parts, not great.

No padding or packaging to prevent the markers from breaking and leaking everywhere. They write on blackboards nice but if you don't wiped off immediately they stain.
