Tangled Shapes Toy

Tangled shapes

While we were shopping around to get some toys for my niece and nephew, I saw some interesting ones for my own. The one we got was a box of small stainless steel shapes tangled together, you need to untie them. It's designed for kids older than 8 years old, but how come I feel it very hard! Basically, you need to find tricks and good angles to untangle them, well, not easy at all. But it's so fun!
