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

Absolutely brilliant product. Not cheap but so quick and easy to use, makes marking on all surfaces so easy, accurate and clearly visible

These have been so useful for marking fixing holes. Makes marking easy on rough surfaces, just a little press and its done. No more struggling.

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!

Arrived on time worked well for me.

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 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.

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.

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
