The #356 black Fold-Over Pouch from OP/TECH is a lightweight and handy way to store a small lens, adapter, mount or other little accessory that you need well-protected. This pouch is made from rugged neoprene and helps keep dust, dirt and moisture off your gear. By cupping your fingers around the top cap portion, you fold the top over the pouch's body. Turn the pouch upside down to completely secure the top. The top is attached to the main body of the pouch so there's never a concern about it losing it. The material is non-abrasive and contains no metal or other material that might damage the surface of whatever you are storing. The pouch is proudly made in the USA and comes with a lifetime warranty against manufacturer's defects.
