Sakurazaka Cafe Postcard I put it in a case immediately after receiving it and have been storing it. I am storing it in a clean state, but since it is stored by a private individual, please consider carefully if you are looking for perfection. I will send it with waterproof and anti-folding measures. If you wish to have a hard case, I will accept it for an additional 50 yen, so please let me know in the comments before purchasing.
