I ordered the shark identification playing card decks, the children's book, and the Shark tooth Christmas cards. All are superior quality and educational. I am impressed on many levels: as a public school teacher, a former SCUBA instructor, and a grandmother, I am excited to share these with my grandsons and my students. I love the connection they can make with actual sharks through use of the QR codes on the decks. I love how the children's book portrays the sharks as necessary and interesting creatures in our environment and not terrifying monsters of the sea. Oh, and the Christmas cards are cute, clever, and printed on quality card stock. Well done! I will purchase again!
