Hi, I'm Vanelle with PhotoFocus with a Studio Tip. Now a professional flag like so goes into the knuckle of a C-stem. Here's a catch. We talked about extension arms before. When you're taking one of these flags and you're inserting the pin inside the knuckle, make sure that the extension arm is coming down at a 45 degree angle. And then when you put the flag in, the flag goes in straight. So this right here is perfectly supported. I'm Vanelle with PhotoFocus. Thanks for watching.
