Ed, lovely pen.
Why only pens for the happy couple, these would also make superb gifts for the wedding party, bridesmaids, ushers etc, even gifts from the bride to groom & vice versa, doesn't have to be the 'one' that signs the register my friend. You could actually do a Wedding party 'set' as such - bride, groom, 3 bridesmaids & 3 ushers say, 8 pens as a set etc. Just an idea
