I got this as a gift for my daughter for achieving her black belt in Taekwondo. According to the online picture, it looked to be about the size of a quarter.
I saw in the reviews that it was smaller than expected, so I assumed it would at least be the size of a nickel or a dime.
I should've listened to the other reviews. It's very small. Tiny. About the size of a hole-punch.
Now, it's two weeks until her test, and I don't have a gift.
