Lovepop first came to life with an imagination meets engineering approach to designing incredible paper art. Now, we've used that same technique to create a magical new line of children's products. Celebrate milestones and create magical moments with Playpop Cards™!    “Ready. Set. Celebrate!” is written on the cover of this speedy birthday card. Upon opening, Lightning McQueen pops up smiling with a “Happy Birthday” message! Celebrate another lap around the track with this fan-favorite Cars character. Any racing fans will adore this birthday card for kids! Size: Each Playpop Card is 4.5 inches wide by 5.9 inches tall and requires one stamp for postage.   Quantity: One Playpop Card with one blank envelope. Lovepop Note: Playpop Cards do not include a pull-out Lovepop Note like our standard cards do.
