FIBO STEEL4-8 Pairs Wedding Business Classic Cufflinks for Men Unique Cufflink Set Mens

Are these made of stainless steel? (color A: 4 pairs)

Do they come in a box?

What is the length of the tie clips in the option "b:cufflink and tie clip set"?

Hey Seller, Do they come in a box or not? I read some reviews saying they don’t and in your description it says it does.
