estar tratado con "guante de seda"?
I know the saying literally means to be treated with a silk glove.. but what does it actually mean?

I thought the expression was "treated with kid gloves" (kid being a baby goat-soft hide)
I think silk gloves goes with a top hat, walking stick and tuxedo.
Below is a picture of silk glove liners to wear inside more durable glove shells.

If the phrase means the same as the English phrase "treat with kid gloves" then it means to handle something very carefully. I'd like to see some native speakers weigh in on this.
