Nature Guide Finder: This nature guide finder has realistic printed patterns, which attract children's attention and allow children to observe plants, animals and even the universe. It can stimulate children's curiosity and promote children's cognition of nature and colors. Happy Learning: Guide children to observe nature through simulated patterns, which makes boring and blunt knowledge vivid and easier to understand. Parents can interact with their children and let them learn in joy, which can help children better understand and explore nature. Double Sided Printing: The natural viewfinder is printed on both sides, which is good for carrying when you go out, because you don't need to go out with 2 or even more viewfinders. When you need to observe the clouds, you only need to use the side with the clouds to face the sky to compare the shape, and when you need to observe the leaves, just turn the side over, which is very convenient. Gifts for Kids: Made of natural wood, safe and non toxic. The size is length (with handle part)*width*thickness: 20*12*1cm/7.9*4.7*0.4in, very suitable for kids use. Encouraging your child to go outside to discover, track, explore, rather than subjectively pass on your perception, is the perfect gift for a child or student. Note: ✔Because it is made of natural wood, there may be some wooden wheels that cannot be eliminated, please understand. ✔Because the size is measured manually, please allow 1~2cm error. ✔When the child uses it alone, be careful not to knock yourself, because the wood is very hard.
