Be!Board B3000 Glass board Marker / pen for whiteboards and magnetic boards, round tip 2-3 mm, black, non-permanent, dry wipe (set of 4)

I've been using these on a glass magnetic dry-wipe board and they are lasting well so far. They write ok and wipe off ok too.No complaints, good product at a reasonable price considering how many you get in a pack.Recommended.

Good product. Ensure lid remains on when not in use or it will dry up.

Arrived quickly and had them a few months now, the pump on the end of the pen makes them last a lot longer

I bought this multi coloured pack but now wished I'd just bought the black one instead as I found the red and green pens very wishy washy. The black is excellent, the blue is quite good but the other two I probably won't use for writing on a white glass board as they are just too faint to read easily. Disappointing.

I bought these to go with my new glass whiteboard and I bought these specifically because they were advertised as being suitable for glass whiteboards. The ink is so feint, that I thought it had run out. However, when trying these pens on a conventional whiteboard, the ink was visible. I tried some other brands of conventional whiteboard pens that I had on my new glass whiteboard and the ink shows beautifully (e.g. Edding 360 conventional whiteboard pens). I'll update this review with some photos if I have time. Avoid these, they're useless.

It's a pen. It's awesome at being a pen. You couldn't want more from a pen, except if it wrote itself. Well done pen

The problem I have with these pens is INCONSISTENCY. Some pens in the pack are great – there's proper color that's opaque, so that I can actually see it. Some are not great at all, in that the ink is very transparent... there's only a shade of black/green/red/blue, etc. I've got over 20 of these pens and only 4 really fit the purpose. That's pretty crap statistics. If the manufacturer can tell me how to make the others write with the same opaqueness as the functioning ones, that would be much appreciated. Please note - I bought these in all colors. The only ones that work tend to be black although the majority of the black pens don't work either.

Great value for money. Arrived quickly and just what I needed.
