Thank you for viewing. This is a Rhythm Card set by Akane Maruko. While it has been used, it is still usable. It seems that it is no longer sold by the manufacturer. All cards and instructions are included, but the box is not. This is an educational material for learning musical rhythm in a fun way. You can create rhythms using the cards and acquire the basics of music. - Brand: Gakken - Contents: • Rhythm cards A34, B24, C62 • Spare cards 17 • Rhythm houses 3 types • Instruction manual
