I will ship with waterproofing and measures to prevent bending. The case is not included. Immediate purchase is OK! I also have many other Reijin-ten postcards for sale. I will offer a discount for multiple purchases. 2-card set: 850 yen (including shipping) 3-card set: 1000 yen (including shipping) 4-card set: 1100 yen (including shipping) If you are setting the price of a single card at 700 yen, the set price will be the above set price + 50 yen. If you choose to buy multiple items, I will create a dedicated listing. Feel free to ask any questions in the comments! For those who want more than that number of cards, please consult me about the price.
