I love these pouches for several reasons. They are well made and I love the draw string closure, because I can use one hand to retrieve another lens. I can never see inside my black camera bag and these pouches help me organize certain lenses for each camera by color. I have chosen one color for each brand of camera. So, at an instant I can look in my bag and see that orange is one camera, green another and blue another. It has helped me organize by equipment and saved time when on the job. Now these are not hard containers, but that is not what I needed since my camera bag is a hard case. It just helps with efficiency to grab and change a lens for a certain camera in an instant.
