Cool

### ⭐ Very disappointed!
*by S***R on June 1, 2019*

Pictures and description are very misleading! Actual product much smaller. Received item together with a softball bat, items was loose in the box and was nothing but crumbles when I opened the box. Very disappointing.

### ⭐⭐ It's fragile
*by A***R on March 31, 2019*

Be careful when you handle it, it starts to crumble. It comes in a hard to open plastic box with zero documentation. It wasn't as lite as I thought it would be. The picture is misleading, it is much smaller.
