Liquid Chalk Pens Markers Coloured Wet Erase Chalk Marker Pens 3mm Bullet Nibs for Blackboards Whiteboard, Chalkboard, Window, Glass, Signs and Mirrors - Pack of 8 by Ezigoo

I used these to draw on windows. The glass has to be completely clean and the pens sometimes need encouragement but the result is good when it works. The selection of colours is good and they are bright versions of each colour however, worth noting if you are using these for glass- there is no black. I haven’t tried these on black boards but they do write nicely on stones and don’t run or change when sealed with clear plastikote spray.

These are perfect for writing on blackboards and the fine nibs mean you can make detailed drawing or write notes.Non messy compared to chalk.

I brought these for my little ones to use on the tuff tray, the colours are get and easy to wash down. We had a issue with the red pen a quick email and the seller was great and is sending out a replacement red. Work really well can’t fault product or the seller. Thank you will definitely buy again

Not easy to use to begin with then failed after one use I’d have returned for refund if my partner hadn’t accidentally binned

Really pleased, super easy to use. Looks great and easy to remove with a couple of baby wipes and kitchen towel. Arrived two days before it was due.

It doesn't rub off clearly can still see writing on chalk board

I guess with something like this it depends on what you use it for. I found that it was too watery and smudged easily. Possible better suited to larger applications

Great pens. Exactly as described and would buy again.
