Send joy in an envelope with this innovative and interactive birthday card! Once the recipient threads the string through the holes in the card and pulls, the little triangles separate and line up in the right order to spell "Happy Birthday!" on a mini hangable banner. It's a memorable way to celebrate the occasion and sure to be a keeper.  Choose from seven vibrant paper colors for the card. Comes with a large pearlescent white envelope for mailing. Also includes a sparkly silver string with aglets (cut just the right length for the banner) in a small glassine envelope. — Details — Front of card: **HAPPY**BIRTHDAY!** in metallic silver ink, Pull-A-Pennant™ directions in black ink Back of card: Pull-A-Pennant™ and Inkello® logos Envelope: blank with square flap Materials: cover-weight paper in various colors, glassine mini envelope, metallic silver string, white pearlescent open-end envelope Sizes: card: 5-3/4" x 9-1/4"; envelope: A10 (6" x 9-1/2") Printing method: letterpress
