The MAVEN Q BOX - Magnetic Photography Filter & Accessory Storage Case

In that Step-Up rings will allow you to use your MAVEN filters on smaller lenses, you may have 5-6 different step up rings. There may also be other accessories you do not want to carry in your main Quick Draw case due to limited space. The MAVEN Q helps you organize these other accessories and not have to worry about them getting lost or damaged being carried loosely in your camera bag.
