 It's a little retractable cap. It attaches to the gun. It retracts out of the way when you're using the gun, but it stays attached to the gun. So, knick-knack, I came up with it. I pushed through. I got the patent through Rita. Thank you, Rita. You're welcome. And I actually got a license deal on it, which is literally, it's like a miracle, but it actually happened.
