NUDGE Liquid Chalk Markers - 10, 6 mm Marker Pens - Wet Erase (Wet Wipe) - Reversible Tip (Chisel & Round Tip)

I have mixed feelings about these markers. About four or five of them didn't worked well when I first received them. The ones that did, I loved them. The ones that didn't, I had to keep pushing the tip to extract more liquid. It was frustrating. I really love the vibrant colors though! They are really beautiful. It's been just under two month since I purchased them and most of them are kaput. I use a couple different colors a day for our family task board so I did use them quite a bit. I would have been nice if they lasted longer. I purchased Quartet brand markers about six months ago and they're still working for us, although they're not as fun and there aren't as many colors. I will be going with a regular chalk board and regular chalk from now on. It was fun while it lasted!

I purchased these markers for a wedding sign. The bride and groom are very happy with the results and so am I. I would recommend you read the instructions and pay attention to the excellent protection provided by the caps. Unlike a popular permanent marker that tends to dry up easily and where I listen for the snap-like sound when capping the pens to ensure they are closed, these markers come with a protective inner cap. I failed to notice the inner cap until it was too late and I created damage to the chiseled ends.Thankfully, the bride and groom have decided to hang their wedding sign in their home after their wedding, and I did not have to worry about any requested revisions. While I successfully tested the paint to see if I could easily remove it, I failed to follow the exact instructions. In one small untested area, a shadow of the paint remained when I attempted to make a small change. I simply covered the small spot with part of the illustration. The couple never noticed.The only aspect more impressive than the pens is the guidance provided by the sender, Nudge Art Supply, Co. This company truly supports you as your prepare to use their product. They provide instructions and encourage you to provide feed back. The service is unlike any service I have received when purchasing art supplies. Outstanding service and pride in their product makes these pens a memorable experience.

I love and hate these. First off, they write well on a black glass surface, which is exactly what I needed them for. The colors are vibrant and clear. But the cap design is really bad. If you shove the cap back on after use (which my kids seem to do repetitively) the tips shred and render them useless. They do come with a couple replacement tips but the issue is just a huge pain. In order for them to last, you have to spend the time to delicately replace the cap EVERY time.

The liquid chalk pens run out quickly and can not be removed from chalk board surfaces easily. They stain the chalkboard so you always see what was written even after it's been cleaned.

BRILLIANT!- Usage: 8'x4' magnetic glass whiteboard for homework & studying.- Drawing large diagrams/graphs on huge surface area can be difficult maintaining continuity of lines & colors. Tried many different types/manufacturers (dry erase, window, chalk) markers. My sister has a small glass whiteboard at work and recommended these.- NUDGE Liquid Chalk Markers are only markers that have worked for us: dry quickly, colors are very bright, hues are brilliant, and coverage is fantastic. Sometimes need whiteboard wipes to cleanly erase color if we leave it on for quite a while ;)- Lucky break...randomly found neon green marker my 2-1/2 year old nephew had taken the cap off of. Pushing down on tip several times revived my neon green marker from a toddler's demise.- Customer Srvc: Excellent! Received personal thank you from company's president & personal customer service (not prevalent these days).- Another ex: sister received box mistakenly w/2 markers of same color, contacted NUDGE Art Supply explaining situation. NUDGE sincerely apologized, sent the missing color + new box.

Got these 10 months ago and liked the color choices and how they worked initially. However, they deteriorate rapidly and some of them never wrote very well. I have a black erase board so couldn't use the black one for it. Used and stored them according to the package instructions, but stopped using them altogether several months ago. I'm going back to using Expo Wet Erase markers which I've had for a couple years and they still work pretty well.

Some of the markers don't release the liquid evenly and the tips are easy to smash if you press too hard. Otherwise, they colors are great and are really vibrant on a black board. I used them on an older white board and were not easy to erase. I would not use on an erasable white board.

Some of the colors fill in well and some of the colors just seem to push around the surface when you are trying to fill the shape in. The reason I gave this such a low rating is because they advertise it as a product that can wipe off with water. However I have had to paint over 3 chalkboards because it is impossible to remove without damaging the chalkboard as well.
