Quartet Premium Glass Board Dry-Erase Markers: Bullet Tip / 6-Pack (Neon)

Beware! Cannot erase these markers after 3+ days of curing! I use dry erase markers to write my weekly meal plan on an acrylic frame. I was able to erase and modify immediately and within first day to make some changes, but by the time the end of the week rolled around, they were absolutely unremovable. I have tried vinegar/water solution, isopropyl alcohol, soap + water, magic eraser, scraping with razor and credit card, and now even acetone. They. Don’t. Budge. Beautiful colors, but I think I would have had an easier time if I had bought actual paint pens?! So frustrating. I may have to get a new frame. I’m really disappointed. (Photo shows writing after all treatments mentioned above!)

If you're using a light board these are the ones to get. Not sure about the 2 whites. I prefer blue myself. The ones that shake allow the ink to flow better. If you shake them very well, which you need to do, they last for a few days before needing to shake them very well again. You need to get the ink flowing. I use these to make professional math videos on a light board. (Look up Berkeley Coding Academy on youtube if you want to see.)

I couldn't get the markers to work but then my students did! They are great, not dried out

I haven't used many other similar products, but I feel that these work 'fine'. The white pen is certainly the boldest/most opaque of the entire pack and it writes fairly well. However, I find it quite that this pen runs out of in after only a few strokes and I have to constantly recharge the tip by pumping it in and out. This is annoying because when you do this it will often drip. This might not be a problem if you were using the pen on a horizontal surface, but I write on a glass board on the wall and no matter how I hold the pen the tip will always run out if ink after a few words. When the white pen is working properly, it is nice and thick but it can be annoying to see the text slowly fading throughout the sentence. The 'ink' in all of the color pens is much thinner than the white pen so the tips stay filled longer, but the result is very faint and hard to read on a black glass board. The pink and the green were the only usable color ones. The blue and the yellow were almost impossible to see because the fluid was so transparent. Another issue with the thinner fluid in the color pens is that it practically gushes ink when you charge the tip so be prepared for color to drip everywhere around the board when using these pens. Overall, these pens 'work' to a somewhat desirable effect, but writing with them is far from an enjoyable or smooth process. I'll be trying similar products from other manufacturers to see whether this is an issue in this product or just a reality of writing with liquid chalk markers on vertical glass boards.

Love that these show upon a black board however they are super thin. I recommend the thicker chalk markers
