Name stamps - white

[orangeplum]

I recently bought a name stamp to name my kids clothes. It's great. However it came with black ink only. Does anyone know of a white or light stamp or ink pad you can buy to name dark clothes as sadly they have quite a lot of dark uniform. Will need to be permanent fabric ink for the wash.

Thanks!

I'm not sure that sort of white ink would show up on dark fabric. I stamp the white school shirts & PE kit (with black ink) and sew/iron nametapes on the rest.
