Marxman Green Standard x2 Chalk Black Deep x2 Marking Pen Hole Marking Tool Set

Excellent idea and work like a dream.i have no idea how long they last but having just moved house they get used. . a lot! Chuffed so 5 stars. Just line up the splines and press for a puff of green or black dust to use as a marker which easily wiped off.

Makes marking drill spots easy - just remember to turn it around to "lock" it, to avoid any accidental discharging!

So easy to use and see the mark on any surfaceThe times in the past when I’ve struggled eith a pencil mark on a wall…. Not any more 🤣🤣Worth every penny

excellent idea, really workable but the dust runs out so fast we stopped using them.. they are too dear for the short amount of time they last..

Excellent product. Would purchase again.

These markers are just what I needed. Could have done with them years ago

The spray system works well through deep mounting holes. I would like a different colour for some instances as green is sometimes hard for me to see due to my colour vision but for most these will be 100% helpful.

I used these when installing pipe work in a factory, very handy when marking clips at height in a dark area.Very good, small and easily used.
