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

Great quality and a great price - Whoever invented these deserves a medal - they work really effectively at marking holes through fairly thick items - wood metal whatever you are trying to mount on the wall - They just work and have a long shelf life between uses

Simply genius! Good product, makes diy jobs a lot easier and a great little gift for someone if you need for the diy person who has most things :)

bright green for marking on dark or black surfaces along with black chalk spray for light and white surfaces. I have used this before many times it is absolutely invaluable. It's an outstanding bit of kit for precision drilling marking accuracy. Very highly recommend.

Uses them several times, time saver and accurate 🙌

Really simple and effective. The less powerful of the two models is now a permanent feature in my toolbox. The conical nozzle makes it easy to make the centre point each time and gone are the days of holding something against a wall to mark a drilling point, only to find my pencil is too fat or the lead is not long enough.

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.

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.

Excellent product. Would purchase again.
