・There are many parts, so I haven't counted them, but please check the images. I had 201 parts when I bought it, but some have been lost or broken, so I think there are about 180-190 parts. (Usable parts for assembly!) I will count them when I have time. ・I counted the balls: 58 balls + 3 fluorescent balls, for a total of 61 balls. Since the balls are small, they are not suitable for households with babies or very young children, or for playing with them. It is dangerous unless the child is old enough to recognize the balls as toys and not put them in their mouth, so please understand this before purchasing. ・Dedicated storage bag (easy to store) x 1 (one of the bag's strings is missing) ・The box is broken and will not be included. [Commitment to Safety] Made from high-quality plastic (food-grade ABS plastic) and does not contain BPA. Please play with peace of mind. Your child's safety is our top priority! However, the accessories are very small. Suitable for children aged 7 and over. [Infinite Ways to Play] It's like a Rube Goldberg machine toy. Children can gradually learn logical assembly through play. It's fun to think about where the balls will go and assemble them. The basic way to play is to connect the grooves to create three-dimensional structures. There are quite a lot of parts, so there are many possible combinations. Children can repeatedly assemble and disassemble them, playing with ingenuity. Simple block shapes can unleash a child's infinite creativity! [Educational Play] The block assembly element fosters imagination. There are quite a lot of parts, so there are many possible combinations. Children can repeatedly assemble and disassemble them, playing with ingenuity. Simple block shapes can unleash a child's infinite creativity! Also, by following the balls with their eyes, children can develop a sense of three-dimensionality. Since they can play with concentration, it seems they can also develop spatial cognitive abilities.
