I am selling this item, which I just purchased and have not used. It doesn't fit my camera, so I am putting it up for sale. I will package it with bubble wrap and waterproofing for shipping. (I will fold and include the box if you need it.) 【Product Specifications】 Length: 110mm (Base plate length: 100mm) Width: 37.9mm Height: 75mm Weight: 95g 【Product Description】 It has a 1/4" screw hole for camera attachment and a 1/4" screw hole for tripods/monopods/ball heads, etc. A hole for a hand strap is provided for easy and safe carrying. Six rubber pads are attached to the base plate to prevent blurring. It also protects the camera's connection surface from scratches due to friction. The corners are rounded. It is safer. The side plate is separate. If not in use, it can be removed with a hex wrench to reduce weight. Depending on the usage situation, the L-shaped plate can be disassembled and used as a single plate. Compatible with Arca Swiss standard clamps/tripods/ball heads/pan heads. Quoted from the website I am not familiar with how to use it, so please research it yourself.
