metal tubing...
Hi guys,
I’m just wondering if certain metals are bad for the skin, PE in general…I made my own Power Jelq device, I use 2 metal rods (not sure what kind of metal), then I have copper tubes (like plumbing copper tubes) around the other metal rods…it works well for me, I’m just wondering if there’s such thing as metals that are bad for the skin that could cause some kind of abnormality or something like that?
