Thank you for looking. This is an old-style Letter Pack Light, the 360 yen version, with 11 sheets. That's 360 x 11 = 3960 yen worth. You can use it by attaching stamps for the difference (70 yen). There are two sheets with stains. They can be used without any problems, but please take a close look at the photos. It has been stored in a dark place at home, away from smokers and pets, but please understand that it has been stored by an amateur. It is folded in half.
