A greeting card puzzle combines the excitement of receiving a greeting card with the joy of completing a puzzle. Our funny puzzle cards include a blank space on the back to write a personal message, or express creativity in any way, before breaking up the puzzle for someone special to piece together the fun inside! We get you started with a humorous friendship-themed sentiment on the front in a fun retro style that reads "Grammar. The Difference Between Feeling Your Nuts & Feeling You're Nuts." After personalizing the back, break up the 60 piece puzzle and place the pieces in the included gray envelope. Everything is packaged in a polybag with an insert displaying easy-to-follow instructions. Due to the shape and weight, extra postage is required when mailing puzzle cards. There's no need to wait for a special occasion or a specific holiday, our Grammar puzzle card is perfect to reach out to friends and family for any moment.
