【Size】Length: 6.6cm, Width: 2.3cm, Weight: 4.6g. Humanized design, easy to install without affecting the use of other camera functions. 【Metal Thumb Grip】Made of excellent aluminum alloy and manufactured using CNC technology, it is not only lightweight and highly durable, but also has a good feel, excellent wear resistance, and corrosion resistance. 【Compatible Models】Specifically designed thumb rest for Ricoh GR III and GR IIIx cameras. The grip and camera hot shoe fit is 99%, providing strong stability, good anti-slip properties, and comfortable grip. 【Hot Shoe Protection】The integrated hot shoe adapter is more robust and secure, protecting the hot shoe from dust, moisture, and dirt. 【Helpful for Photography】The grip conforms to ergonomic standards, maintaining a 22º angle between the thumb and the camera, distributing pressure more evenly across the thumb's surface. This design makes holding the camera more comfortable and helps in taking high-quality images! Purchased on Amazon in September 2025, but never used, so I am listing it for sale.
