This is a very high quality hedgehog in a cage puzzle. You won't find a puzzle like this of this quality anywhere else.  It is made of aluminum so it is very light and very sturdy. 
The puzzle of this kind has been around for quite awhile.  It is tricky to get the spike ball out of its cage.  The twists and turns used to get it out make it quite challenging to some and frustrating to others.  The cage is made from one piece. The Hedgehog inside (ball) is from durable material, it has 10 spikes and it is not separable.
Measures approximately 4.5 cm diameter x 8 cm tall / 1.8 in diameter x 3.2 in tall.
