70s 80s vintage Taiwan hobnail glass votive candle holders, amber w/ worn ruby stained color

Vintage Taiwan hobnail glass votive cups, amber glass showing beneath the worn ruby flash color. This is a set of four matching pieces.

There's no chips or damage to the actual glass, it's just the color that's scratched and worn from use. The color would come off with a soak and scrubbing, I think - I've left them just as I found them.
