Wedding gift

As you know I will be attending a few wedding parties.  This is kind of challenging when it comes to select gifts for the bride & groom.  I want a gift that is useful & yet is memorable.  I stumble upon this website which personalized the wine bottle for the couple.  The bottle is engraved with personalised wording or image your desire.

I think this is a great idea as a wedding gift as it is personalised & they could still keep the bottle for future memory.  What do you think?
