I am selling this item because I was unable to install it after purchasing it. It is a new, unused item that was only opened for the purpose of taking photos. A cold shoe mount is designed on the top, allowing you to set a microphone or light. Compatible with smartphones from 57 to 84mm. Non-slip silicone pads are attached to prevent scratches on your smartphone. Made of aluminum alloy, so it is very durable. - Color: Black - Material: Aluminum alloy - Compatibility: For cameras with 1/4 inch screw holes - Included: Mounting wrench Thank you for viewing.
