The container of the cache is small size and white color...
You can use ball point pen for logging, but I suggest for you to use a Name Pen (Oil-Based Pen), because the log sheet of Cache is made with plastic.
After logging, please carefully lay on original location and covered with small stone...
In Korea, most of the children (boys) had played "ICEKEKI" which is Korean Children(boy)'s play, the play is that boys suddenly raise some girl's skirt..
Why don't you play "ICEKEKI" ?
