1mm Extra Fine Tip Chalk Pens (10 Pack) Neon Color Liquid Chalk Markers | Non-Toxic, Wet Wipe | For Blackboards, Chalkboard, Window, Glass

When the ink flows well they look great but my experience writing on windows was really difficult, it was like using a biro that was running out, needing constant shaking and turning around. I struggled to even draw a simple line.The nibs are not secure either so when I took the lid off the first pen the nib flew out and is now lost in my garden. I had to be really careful taking the lids off the others.The intention for purchase was to find a fun way of teaching my little boy to write and draw but my experience unfortunately is that they are far from suitable.

It's such a shame, these pens would have been great but they came with one nib missing (black) & there's no way to get in touch with the seller & arrange a replacement - we didn't want to return as my daughter wanted to get on & use them for a project - they're quite expensive to have one whole colour effectively missing, very disappointing!

I am very disappointed 3 out of the pack are not working properly. If it wasn’t for the fact I needed these desperately for a project I would return them. As it is I 2 of the colours I need do not work but I will just have to cope with the few I have. The ones that work are good. But honestly truly disappointed. And cannot even contact the seller. Only option is to return!!

Easy to use. Took a while to get the ink up the pen tip. Most of the pens in the pack work really well, a couple need a bit of coaxing! Lovely having the range of colours and the thin nib is ideal for jar labels.The pen stays on fairly well, but can come off a bit under the warmth of a finger. Wipe off easy and change label name which I like.

These are very disappointing. I don't want to waste anymore money by sending them back. I spent some time getting the ink to flow on all of them, only to find the ink stopped, you press the nib to start the flow again, then you write about 3 letters, then start the process again...very frustrating.

I used these with labels for elderflower bottles and jam jars. Really like the colours, and good quality ink.Had to use hairspray over the top of chalk writing otherwise it just smudged and smeared off, but hairspray seals it off and stop this happening.

I loved the thought of these, but when they arrived, I tired all them, took ages, but they don’t all work and the ones that do work constantly need to be shaked and tested before use. I will not be buying these again

I bought a set of these less than 3 months ago I used one colour at the time and it worked OK, I've just gone to use them again and none of the colours work, not even the one that had worked, I've shaken, pushed the nibs repeatedly, cleaned the nibs and nothing. I need them urgently for a class I'm teaching this week, so glad I tried them out today, I've just had to ordered another pack of a different make, hopefully they will work , very disappointing.
