These are laser cut from 1050 grade aluminium from my unregistered design right and are 1.5mm thick. They are approx 12mm x 150mm. There will be a nobble which is formed where the laser starts and finishes which can be removed by gently filing it. There might be some light surface marks which will be removed when the blanks are polished. The blanks will be supplied unfinished so some polishing by hand or in a tumbler might be required.
