These are sets of FOUR Handmade Cards and coordinating envelopes.  Both were made of cardstock so they have a classic luxurious look and feel.  They measure 3.5" X 5.25".  They would make nice little gifts  or just to have on hand when you want to send a note to someone special. The envelopes come with a double sided tape strip for sealing.  Each card is unique - no duplicates.
