This is a Katakana board. It's a set of voiced sounds (dakuten), semi-voiced sounds (handakuten), and contracted sounds (youon). The contents are as shown in the photos. The Katakana card magnets are processed to a thickness of 5mm, making them easy for children to hold. A Katakana voiced sound chart is attached to the board. Katakana card magnets with magnets are placed on top of it. You can study by arranging them in the same way as the chart. The Katakana voiced/semi-voiced sound card magnets are 2.5cm x 2.6cm, and the Katakana contracted sound card magnets are 2cm x 2.5cm. The material is laminated paper attached to a styrene board. The board size is 20cm x 30cm. *If you purchase this together with the Katakana board, which is sold separately, you can create more words and learn more efficiently. Hiragana boards, Hiragana boards (voiced/semi-voiced/contracted sounds), and Romaji boards are also available. Although carefully made, there may be some slight misalignments due to being handmade. Please understand this before purchasing.
