Bought to mark hole on corrugated iron roof for flu on my shed. Doesnt fit a sharpie marker or carpenters pencil. Only able to fit a small pencil. But good apart from that

I bought this because I had tried to make my own compass several times for woodworking and failed miserably. So thought time to buy an actual compass. Not only does this not leave dints in the timber like my own made ones. It sticks much better and I get a much better finish than the compasses I tried to rig up for myself. In the end I wish I had just bought the right tool for the job to start with. As this is better than anything else I could come up with.
