This is a very small green plastic container almost 60mm long. Once upon a time it contained matches and they would survived a swim in the river. Nice water tight container - as long as the cap is replaced correctly by making sure it clicks.
It has room only for the log.
Update May 2017. Now onto te third container - looking for pill containe inside a Berrocca tube. Please lift it out of the 'carrier' and replace exactly as found.
