What is the optimal action to take regarding clothes that were sewn but their owners have not come to collect them for years, knowing that the fabric belongs to the customers?

If one despairs of reaching the owners of money, it should be spent on charitable causes and for the benefit of Muslims. Therefore, if you despair of reaching the owners of these clothes, it is permissible for you to sell them and take your wage from them, if you have not already taken it, and the remainder should be spent on public welfare.
