Kamiquasi on TOL-11704 - Hakko FX888D Soldering Station

The regular sponge (in the front) is a more gentle cleaning option compared to the wire one, and doesn't clog up with excess tin as much over time.
I have no idea why the photographer decided to put the wire one in the back, though. It's supposed to go in the little curved slot at the front - yet it looks rather comfy where it is, too, so all that open space must be useful for something :)
