Children Know Everything Volumes 1-4 (Complete Set) I'm watching this in my spare time, so I'll reply as quickly as possible. Shipping will take 1-2 days. It will take 4-7 days if I am on a business trip or away from home. I will ship the items compactly. Thank you for your understanding. I am not accepting price negotiations. Please purchase at the listed price. Based on Mercari rules, priority will be given to the person who purchases the item, even if negotiations are in progress. Thank you for your understanding.
