Is it appropriate for my sister to send my brother and sister-in-law a couple cup?

Suitable.

1, the relationship is really close to a certain extent, such as close family elders, or lovers or girlfriends. Sending a cup will not only mean tragedy, but will increase the feelings between each other.

2. Sending a cup means "for life"; You can send cups, but you can't send cups at will. A cup is usually considered to have a lifetime meaning.
