This is not a typical engagement card. This is an 'Oh my god you went and did it, that's amazingly fantastic you wonderful, beautiful, stunningly awesome couple!' card. 
 
A striking black and grey fold-out concertina card that speaks the truth. No frills. Just a truly heartwarming message to congratulate the happy couple on their engagement. Also available as a rose gold greeting card if metallic foil is more your thing.
