The Ulanzi ST-06S is a 360-degree rotatable smartphone holder. - Brand: Ulanzi - Model: ST-06S - Color: Black - Function: Smartphone holder Thank you for viewing. This is a smartphone holder that can be attached to a camera's hot shoe. I used it once in a park, but the size of my smartphone barely fit even after removing the cover, so I found it inconvenient and bought another holder. This holder requires a 1/4 screw to attach. If you need it, please comment, and I will include it at no extra charge. If there is no specific mention, the holder will be sold as is. However, please understand that this is an inexpensive item purchased online, so please only purchase if you understand the quality.
