Tour Penlights - Law of Inertia feel daCITY ON eST TrackONE IMPACT Rough "Stone" (LaFST) The feel daCITY Law of Inertia penlight has not been taken out of its box and is almost unused. The other three are either out of batteries or do not light up, and I have not been able to confirm that they work. For fans, how about adding them to your collection? Please purchase only if you understand that these items are stored at home. I plan to list other SixTONES items. If you have any requests for combined shipping or separate sales, please comment.
