Supervised by a children's classroom! All blocks with sounds ♫ Retail price: 5,500 yen "Sound-filled Blocks" & "Sound-filled Blocks Volume Set" Easy to grasp and stack, perfect size. Yet, not heavy! The secret is... the blocks are hollow to accommodate the sound mechanisms. They have a moderate weight and are large enough to prevent accidental swallowing. This is one of the key points that allows you to let your child play with peace of mind, as they can shake them, hold them, and feel the texture repeatedly. "Success!" leads to confidence, fostering a spirit of challenge and curiosity. The blocks have a warm wooden feel and gentle colors. Even babies who can't stack blocks yet can start by having adults make the sounds for them, and gradually enjoy the rattle play by shaking them themselves. They can play by knocking them down, stacking them high, and so on, allowing for various ways to play as they grow.
