The inside is clean, but there is some yellowing on the edges due to long-term storage. There are stains on the cover due to deterioration. I have checked it once, but there may be some writing inside. Please be aware that there may be a signature of the owner. I hope this will be helpful for those studying balance. I will also be listing other old training course texts, so please take a look. If you purchase multiple items together, price negotiations are also possible, so please feel free to contact me.
