I think it's not too difficult since adults were making it. For those who understand that this is a used item, thank you. Shipping will be done with simple packaging, only waterproof. [Items to be sent] Everything in the third image. ・Straws (31cm) 64 ・Joint balls 36 ※The green cloth in the image was originally sold separately and is not included. [About the product] There are a total of 100 pieces of tubes and connectors. The straws are 31cm long, so you can quickly create large works. After you make it, children can go inside and play (*^^*) They were happy when they made a building and covered it with sheets, making it like a tent or a secret base♪ (The straws themselves are not strong enough to support a child's weight, so please be careful as they cannot be used like a jungle gym). The connectors can be inserted at various angles, which is convenient. The target age is 5-12 years old, but if an adult makes it, it can be used from a younger age. The straws are stiff and cannot be bent into an arc. They can be cut shorter with scissors, etc. Through play, children can enjoy and develop concentration, creativity, curiosity, sensory education, and finger training, allowing for play and education at the same time. While freely creating what they like, they develop imagination, composition skills, and spatial awareness. It changes into a three-dimensional structure in an instant, not just a flat surface.
