oppaakirjat
Oppakirjat, also known as opaque books, are a type of book that is designed to be difficult to read. They are often used in educational settings to teach children about the importance of reading and to encourage them to read more. Oppakirjat are typically printed with a special font that is difficult to read, and they may also have a glossy cover that makes it difficult to see the text inside. The books are usually filled with nonsense words and phrases, and they often have a humorous or whimsical theme. Despite their difficulty, oppakirjat can be a fun and engaging way for children to learn about reading and to develop their reading skills.
