Glass Pen Window Marker: Liquid Chalk Markers for Glass, Car Marker or Mirror Pen with Washable Paint - Car Windows, Mirror, Storefront Windows, Parade & Party, Holiday (Red, Fine Tip)

I should have read the reviews better. I was putting lines up on my windows to stop bird collisions. It's still pretty thick (at 5mm) and after a couple of windows it had a hard time chalking. Got sloppy and I had to push the tip in a lot. Would not buy again.

This pen was awesome! I purchased this along with blue, white and black. I used it to draw on my car for a drive through graduation. The black showed up even on my black windows which was awesome! Colors were so bright - even 2 weeks after (still haven’t removed it...)! One or two of the colors were very leaky and dripped when I was not holding pen with a paper towel around the tip, but that was rare. When this happened or I made mistakes, I sprayed and wiped the window with a paper towel and it was clean to try again. I highly recommend!!

I'm a school librarian, so I'm constantly looking for ways to decorate the library. My library has large windows and I use these for decorations. I have tried many products for writing on the windows, but haven't found a lot of products that write well, have bold colors, AND, easily erased. I bought the larger nib and did a test area. It had a bold color and came off so easily!For a large pen they are a little expensive (like most educators, I'm buying this out of my own money) so I hope they last a decent time. Wish they had fun colors like metallics and glitter, but it is a good start.

I thought this was good. The white seemed to pop and remain as solid as when it first writes on glass. It stayed on without any rub off. You have to use a wet cloth to remove. A dry one didn’t make it budge which is probably a good thing. The red in the pic was chalk paint and that rubbed off with a dry cloth while the rest stayed put. Pretty solid product.

I don’t know if I did it wrong but it did not look anything like the pictures. Every time I would write it would get all splotchy and I would have to go back over it and it still didn’t look nice.

Its like a sharpie for glass. I use it to write on car windows for work (I work in a claims office). Wish that it dried a tad faster because if you touch it for any reason right after writing it will smear. To take it off I use a windex and a paper towel and it comes right off.

Wrote great on auto glass, and washed off easily after baking in 100 degree sun for 4 days at a festival. This is what you need

great alternative to a paper labels for concoctions I store in colored glass or plastic containers. I do notice that after much handling ( for example, a salve I stored in an amber glass jar and used every night for a couple of months), the lettering is disintegrating by the time I got to the bottom of the jar. On the other hand, if you are recycling the jar, the lettering comes off easier than a paper label! We use this pen to label wine bottles that are used for one or two nights or potted seedlings and then cleaan and recycle for the next harvest or planting. It works perfect.

Arrived really quickly and works really well. Bought it just for a bit of fun and it was a hit with all the family members . Everyone wanted to draw on our Xmas window. Some people actually thought it was stickers........have found that the best way to remove from the windows is to use a steam cleaner.

I purchased two of these pens as I wanted to decorate all of my downstairs windows for Christmas and I didn't know if one pen would be enough, however, I only actually needed one pen, so a little does go a long way.To use the pens, you just need to press down on the nib a few times to get the ink flowing. I did this on a piece of paper to prevent any dribbles. You then just write, or draw whatever you want on to your glass.There was a point where I thought that the ink had run out, however, after dabbing the nib on a piece of paper again, the ink began to flow again. I suppose writing horizontally, rather than vertically messes with the flow.The coverage of these pens is excellent, and long lasting. I decorated my windows at the start of December, and I have just wiped it off now at the start of January. The ink would have been fine to stay on longer if required. Incidentally, all I needed to do to get the pen off the windows was to wipe it over with a warm wet microfibre cloth and give it a bit of a scrub. The ink will not just wipe off if you accidentally brush past it.I would definitely recommend these pens, and would buy them again.

Very happy

I tested it out on a glossy black granite kitchen worktop. I gave it a good shake and pressed down on the tip to get it started. The white flowed well and totally obliterated the black writing surface. I left it overnight and (despite it being on a shiny surface) it seemed to stick well and wasn't easily wiped off, which means that it is unlikely to be rubbed off if someone brushes up against the writing. But it came off easily but not too easily when wiped hard with a dry cloth.

Just like in the movies. Also I recommend going for this thickness of marker because I tried a thinner one and it doesn't write anywhere near as smoothly; you know because of the thinner tip less liquid can soak in it and so you end up with there being "invisible lines" where you were writing if you get me. (Thinner one writes like an nearly out of ink pen, it's quite unpleasant). Oh yeah for all you scientists out there; I bought an acrylic plastic slab to write on and it works perfectly.
