J.B. Camera Designs Pro Bamboo Grip-Base for Sony A7 A7r A7s - Handmade in the USA J.B. Premium Bamboo Grip adds improved ergonomics, increased protection, and unique look to your Pro Digital Camera. Due to demand of our handcrafted product - please pre-order and I will ship by the "Release Date" listed here. My Bamboo Grip-Base is made of strong sustainable Bamboo and offers a lot of protection to the base of your camera and that little bit of extra grip area for your 'pinky' finger. Each J.B. Bamboo Grip Base is beautifully unique and over time, the oils from your skin and any dings will only add to the awesome look of the Bamboo Grip. J.B. Bamboo Grip-Bases are designed for full access to the battery and memory card compartment while attached. Tripod threads are also fully available through our custom Tripod Attachment Screw. Bamboo is a great material for camera grips because of its natural properties: incredible strength while being lightweight and the natural grain texture it provides for grip. Every Bamboo Grip I make is guaranteed for life and I stand behind this handcrafted, made in the USA (Oklahoma) product. Thanks! - J.B.
