The Stealth Gear Pro gray gradient filters are interchangeable with the P Holder Cokin system. You can use different filters in the same container system. Because the filters are flat, they are easy to store and carry. The advantage of these longer filters is that you move up or down to move the transition from the gray filter because usually your horizon is not in the middle.
