Window Chalk Markers for Cars Glass Washable, 8 Pack 10mm Jumbo Liquid Chalk Marker Pens Chalkboard Markers,Window Paint Washable Markers for Car ...

I love these washable window markers. They're easy to use and come off easily with water, making them perfect for friendly pranks with your family. I look forward to getting a lot of use out of them in the future.

I do not recommend this product. Its made for car windshields, any moisture, such as due or rain removes it. Not recommended.I

These are so neat! Theyre like liquid paint markers, but the paint is liquid chalk so its not too bad to clean up. The tips are nice and broad and the paint flowed easily.

The markers draw fairly smoothly. The white marker seemed a bit streaky, possibly because the paint did not fully saturate the tip. The other colors worked smoothly and was easier to tell when the felt tip was filled with paint and ready to go. It does take a bit to get the initial flow going to the tip though. The colors are vibrant and full. The yellow is very bright and almost florescent in color. We use paint markers to keep a welcome board in our entry way at home. It is a part of my wife's seasonal decorating around the house. We have only used them on a black caulk board surface, so I cannot speak to how well they work on glass or other surfaces.

The directions to get these started are wrong. We're told to shake them, then press and hold for several minutes to get the chalk resin to flow down into the nib. Doesn't work. I literally sat for 20 minutes with one pressed down, no luck. Instead shake for 30 seconds (tried it without this, was much slower to work), then push the nib in repeatedly by pressing down hard enough to push it up into the reservoir. Keep bouncing it in and letting it out until the chalk starts to color the nib, ~ 90 seconds. Then, press down and hold until the nib is saturated, takes ~1 minute. If the nib is fully saturated, they will start right up the next time they're used. If the nib is only partially saturated, you'll probably have to repeat the saturation procedure. Some of the nibs were loose and partially out when the cap came off, I just pushed them back in. Once saturated, they seem to be staying in just fine. Once they're flowing, these markers are a lot of fun. The colors are bright, proper neon, and the blue and white are totally opaque. You can get some interesting effects by putting two colors close together while both are wet, they kind of flow together. You can get a sharp edge on the chalk by rubbing a finger across it while pressing firmly- they come right up! However, if only pressing lightly, they stay put. Basically, these are going to be long lasting if used on windows, and not intentionally erased, but they do come up easily when you're trying to get them off. The red leaves streaks, which come right up with water, but I'm betting that if left on a plastic surface for a few days, the red might stain the surface permanently. Just FYI. Strongly recommend starting the chalk flowing before letting the kids see these markers. They're having a ton of fun decorating our windows, and I'm pretty sure this is one of those art supplies that I'll have to make sure they're still working/buy a pack of every time there's a holiday or birthday in the house. Also nice that coloring paper will never be an urgent errand again, to protect my last pack of printer paper! They're not perfect, but for the novelty and joy they're providing, they're a good product at a reasonable price point.
