My stonewashed TI Pineapple mini Seigaiha. I found the seigaiha ridges around the end of the tailcap made it uncomfortable to operate, so I sanded down the rough edges. Then decided to go for it and sanded the entire thing smooth. Now it's much more comfortable and there's a nice contrast between the ridges and grooves.
It's a pretty little EDC light. So compact and easy to use, with a nice floody beam. I do find it a little odd that the seihaiha pattern faces one direction on the head and body, and the opposite direction on the tailcap, but I suppose that way it works regardless of which end you stand it on.
