This engineers french chalk pencil is a perfect marking chalk for bricklayers, engineers, welders or general construction because it:
– doesn’t snap or powder as easily as other chalks and is virtually dust free.
– has a high heat resistance and remains visible when heat is applied ie. when cutting / welding.
– leaves sharp white lines
– is water resistant, but is not permanent.
– copes well out in the weather – it is not going to dissolve
Chalk Size: 75mm x 10mm x 5mm.
