This is a book compiled by carefully selecting topics from the NHK Radio Practical Business English course. The complete edition (blue cover) comes with two CDs. Please note that the red cover edition does not include a CD. I'm sure I didn't throw it away, but I can't find it... I don't think there are any major stains, but the red cover edition shows noticeable discoloration and wear due to its age. This is for people who just want to be able to read it. Feel free to comment or request a price reduction (though I can't guarantee I'll be able to meet your expectations...). Purchases without comments are also welcome. Shipping will be via Rakuraku Mercari Bin or Yu-Yu Mercari Bin. I've set the shipping time to be longer just in case. I think I can usually ship within two days, unless it's during the New Year's holiday or other similar periods.
