Premium silicone material: Our capybara cars are made of ultra-soft silicone. With this material, they can be posed in any number of ways and have any number of fun collisions. Because it is a sealed package, you will smell a strong odor after opening it, but it will weaken after 48 hours. Ideal size: Our capybara cars are 3.62×1.96×2.75 inches in size, compact, and weigh 0.48 pounds. Due to their small size, boys and girls can easily hold and play with them, and the surface is smooth and soft. Squeezing them or wrapping them around each other can easily restore their original shape. Fun creativity: Twist, shape, pose - the possibilities are endless! The soft, comfy feel is perfect for when you need a break, and they are perfect for indoor and outdoor play! Flexible and soft toys like this can even help those who are sensitive to sensory and visual stimulation. Fun gift: Their stress-relieving properties make them excellent ideal gifts for kids and adults on children's day, birthdays, and Christmas, great companion toys for adults and students to stretch and squeeze stress and anxiety relief.
