The best crown! Our party hat greeting cards are super fun and adjustable for the perfect fit. Tell someone they are the best and let them wear their crown with pride all day long! Each is made from eco-friendly card and comes with an envelope made from a mix of recycled paper and citrus peels that would otherwise be headed to landfill. Made by Hadley from an original artwork, their cards are made from high quality recycled and eco-friendly boards.
