Dear all please I need ideas on how to put an indelible ( what can not clean) mark on shoes so I know my shoes when I go visiting, auditing, and counting my shoes with my sellers (13).

Due to the fact that they take shoes for different prices and in large quantities, they atimes paly smart by selling the once of N1500 and replace it with the one of N700. just to make excess gain at my own loss

This have been a problem in business so far and I need help in tagging each shoe according to price. so it can't be swapped, cleaned and can help for easy record.

any ideas please

Thanks

Look for a hot stamp and customize and press them against the sole.... Thieves dem
