Thank you for viewing. This is the leg of a JOBY Mini Tripod GorillaPod 3K PRO Kit. It's an older model, so I don't know the exact model number, but I believe the leg socket is made of aluminum. There are some minor scratches, but the condition is good. Used only indoors. The frequency of use was not high, but please understand that this is a used item. Although there is no head, how about using it with your favorite head? Please consider this opportunity.
