Climber Girl is a fun shape that offers edge-like places to grip on like the arms, body, and legs, while the sweet spot is when grabbing her head. The head is approximately a 2" round with a flat back, which feels similar in size to a golf ball. Her ponytail adds width for a 2-1/2" wide grip.
The arms stand 1" off of the wall and are 3/4" thick
There are many uses outside of climbing for a shape like this such as a Christmas Tree ornament and as a Women's bathroom door sign.
Whatever you choose, you are sure to have fun with him.
