Thank you for viewing. My child used this, but is no longer using it, so I am selling it. The rubber is not stretched out. I think it's relatively clean. I want to sell it at a low price, so I plan to send it by post, and will flatten it for mailing. Therefore, please understand that the packaging will be simple. The "Squish" hand toy, a long-selling product from Manhattan Toy in the United States, can be played with for a long time, adapting to the development of fingers up to around 1 year old. Hands are also called the "external brain," and using both hands in a balanced way activates the brain. It allows for experiences such as seeing, hearing, grasping, and rolling, which also leads to daily actions like writing and holding chopsticks. The "tensegrity structure" = maintains balance with the pulling force of wooden sticks and rubber, and the design is easy to grip even with small hands. The way it collapses and returns to its original shape no matter where force is applied stimulates a baby's curiosity.
