Wedding Gift Chapstick What Is The Appropriate Wedding Gift If I Did Not Attend The Wedding?

What is the appropriate wedding gift if I did not attend the wedding? - wedding gift chapstick

My friend and his wife were married in Europe and my husband and I could not go to the wedding. They were at our wedding two years ago, and I have no idea what is the appropriate wedding gift? Give them half of what they gave us, they should pay us for your wedding? Should I get a check or even a few things on your registry? I do not want to offend you, but no idea what I should go, please help have.
