Meiji Curl School Entrance Exam Packaging

Each of these packages (the whole package) looks like one of the religious charms sold at Shinto shrines for good luck when children take their entrance exams for various school levels. One is cheese flavored and the other has a light flavor.
There is also a play on words were an u (う) is added before curl, in order to make it sound like ukaru (受かる) which means the take in take an exam.
