Charles Bentley Twin pack Marxman chalk NON-Permanent DIY Marking tool pen

Gives an almost luminous green spot, to mark the required drilling position, even down a deep hole - for example, marking drilling positions through a 75/80mm thick timber batten onto a concrete wall or post. An excellent but essential piece of kit for your toolbox, which I thoroughly recommend !! Just remember to shake before each use!

This is the second set I have bought and frankly it would be hard to manage without them now. Invaluable to mark surfaces for drilling and screwing through a hole in any appreciable thickness which a pen or pencil won't go through - there is a version for thicker materials.Particularly useful to mark brickwork, which is notoriously difficult with a pen or pencil.

I saw this product on Dragons Den and bought it for my partner. He’s really impressed! Really easy to use and does a good job. Perfect for any toolkit.

Arrived on time worked well for me.

I saw a fellow Locksmith using this product on his YouTube channel to Mark out where the holes were for a hinge so that he could drill into a metal fence and gate frame. He also used it on a brick surface to put a wall safe on. I thought the design was genius it's bright green. It's chalk it rubs off and if you get it on material fingers it rubs off. It's an absolutely genius design very simple to use very small so it fits in your kit bag very good price absolutely hundred percent. Recommend this for any Locksmith or anyone wanting to mark a hole on any rough surface or smooth surface it's brilliant it's wonderful it's fantastic. I love it. I have two in my kettle ready.

as my title says why I did not find these earlier in life they make marking the walls up so much easier when you’re doing DIY I can’t believe I’ve only just found them but I will never look back

These take the hassle out of marking up a wall or any surface area much need either screws or marking points .Here on Amazon I found them cheaper than in big DIY stores .These last as long as you reseal them and just easier to use than a marker or pencil . It’s chalk so just wipe off and even the smallest of holes made easier with this great little invention

These are great pens for marking drill holes, I've used pencils and many a sharpy but they don't last. The only problem I found was one that I had not used when I came to needing it, had no propellant in it so it was useless.This would not be sellers fault, good price fast delivery.
