UMBRO Boys M Pants / with minor defect

These are pretty much in great condition but the bottom leg zippers (shown in image) do not work. The metal has a tiny bit of corrosion on the zipper causing it to stay in place - however I’m sure a tiny bit of cleaner such as CLR might help remove this! My son only wore these a small handful of times, he likes them better zipped anyway, but they look great, perfect for cold outdoor soccer practice days!!
