I'm afraid that this traveller has gone lost together with cache Ugglans park according to DNF logs December 25-26, 2011. Both logs say that the screws remained, but unfortunately no box.
Cache owner hguo has in e-mail to me (Memme) to-day confirmed that no TB was in the box when he enabled the cache on January 1, 2012.
TB owner or cache owner, please move the traveller to Unknown Location (Mark Item Missing) if it doesn't show up soon.
