"Sukkiri Tokeru Registered Sales Representative Past Question Collection 2020 Edition" by Hisahiro Mizuya / Sachiko Endo Price: ¥1500 #HisahiroMizuya #Hisahiro_Mizuya #SachikoEndo #Endo_Sachiko #Books #Nature/Medical_Science/Health The red sheet for the summary notes is not included. Most of the stains are on the summary notes. I remember spilling coffee on them. There is no odor. There is no dirt or writing on the inside of the main book. I think there should be no problem with use, but what concerns people varies, so I hope you will take this as my subjective opinion."
