Benesse Worldwide Kids Stage 0 Toy. Musical Building Blocks, set of 10. These blocks make different sounds depending on the color when shaken. These blocks were specifically designed for Worldwide Kids to match the consonant sounds "k" and "t," which are difficult for Japanese people to master. They are designed to help children learn consonants while playing. They increase interest in and concentration on sounds, and cultivate the "listening ability" essential for language acquisition. I have included a picture of a block with a scratch in the second image. There are some minor scratches, but overall, they are in good condition. I am also selling a full set purchased in 2019, and I will include other Stage 0 materials (DVD/CD/Parents Guide) for those who purchase them together. Please make your request through the combined purchase request. I also specialize in educational toys and will be listing more items regularly. Thank you for your interest.
