A ring of gold of no choosing.


However, when you rotate it with your fingers, a strange sight appears.


As the eye of the weave opens and closes, an illusion appears as if the ring is stretching and shrinking.


Of course the size of the ring has not changed.


This ring is on sale at the following site for 5 dollars 99 cents (about 560 yen). Various toys using illusion are sold here as well.
