[Hasegawa, Shoda]
We have sent the spare mirror to Kashiwa using the Perican box labeled as 'KAGRA PRM'.
The wooden box that was sitting inside it was removed from the perican box. The wooden box is now in Kashiwa.
Inside the Perican box, we put the flags, wire breakers, and some gluing jigs.
Also, we sent the gluing tools such as glue and scaler packed in the plastic case.
During closing the mirror box, I found a small crack on the spare mirror. (it is difficult to see via photos.)
We do not know when it was made.
