I have read everything. Only volume 2 is missing. I will package it in waterproof packaging. Please feel free to contact me if you have any questions. *Even if you are negotiating a price reduction, we will prioritize customers who purchase immediately. Thank you for your understanding.* [Discounts for bulk purchases] I sell various items such as books, clothing, and miscellaneous goods. I accept bulk purchases. I can also offer discounts, within limits, so please consider it. *To reduce plastic waste, I reuse packaging bags from other products as much as possible as Mercari packaging bags. I choose clean ones, but if you are concerned about it because they are reused, please let me know. I will pack it in a new bag.*
