"stainless" tee-shirt?

Last year I bought a "stainless" tee. I saw it worked at first, but now it has some discoloration. Do these things expire or something?

I have never heard of them before 😊

🤔 me neither, do they make them for kids?? sure would love that, Aaralyn is rough on shirts! (paint, markers, mud, ect... 😉 )

i need 1 of them for weaning it'd be great (why does every kind of baby food have to have tomato in it) and (why is all kids clothes white or v-light)

I live in Canada and got 1 at Mark's Work Warehouse. They're quite cheap. Mine was no more than $8. I'm not sure about kids clothes. That was the only place I've seen them. But I don't shop for clothes at very many places.
