Everworks Liquid Chalk Markers for Glass Boards, White Boards, Windows, Dry Erase Boards, Blackboards and more/Perfect for Art, Offices, Schools and Home Use- Thick Chisel Tip & Set of 4 Markers

I threw the packaging away before I learned that you have to depress the spring loaded tips to prime the markers. Some reviewers didn't know this, and said the markers didn't work (called them a scam.) The markers work extremely well once they are primed.

The markers looked pretty, package came opened. Markers were clearly never used. It worked well the first time and second time onwards, none of the markers are writing properly. Don't waste your money buying them. I would give ZERO stars if I can.

These liquid chalk markers are so nice! I initially purchased them for my glass blackboard, but my kids also found that they work great on ANY glass surface, including our windows! They also wipe off clean with little effort.Each pen has a transparent barrel so you know how much is left in the marker, and you can re-moisten the tip simply by pressing down on the tip for a couple of seconds. I look forward to creating some window masterpieces with my girls on rainy days. ^_^

These arrived with hardly any liquid chalk in them. The blue also had what appeared to be burnt product. No matter how much I shook the pen, the brown burn would not mix with the rest of the product. The yellow was also discolored. I thought these would be a good value after reading the other reviews but it was a waste for me. Next time I’ll pay the extra couple dollars to get better quality. Two thumbs down.

I use these to write myself notes on my back window as reminders. (Like to remember to bring my laptop with me to work. :) )

I received these markers today and there is quite obviously something wrong with the blue and red. It does not appear the issue will be resolved with a little shaking... it's like their soul has died. I will not be using them. Boop! They are going in the mail to be returned.

The pens are hard to get going the first use and they don’t show up well on a black dry-erase board

These are great. And they wipe off easily, which is important.
