Height: Approx. 32cm Width: Approx. 28cm With gusset There is a gusset, but since it is unopened, I cannot measure the size. Please check the photos I will upload. (It's hard to see, but) It looks like an A4 size will fit perfectly ★ It is new and unopened, but it has been in someone's possession once, so please refrain from purchasing if you are sensitive. It will be folded small for shipping. ◎ The price includes shipping, fees, etc. ◎ Please comment before purchasing to prevent complaints. ◎ It is stored at home, so please refrain from purchasing if you are sensitive. ◎ I have children, so shipping on weekends is generally difficult, but if you absolutely need it quickly, please comment. I will do my best to accommodate. ※ In the past, my rating was lowered for no reason, which made me feel very bad. I want us to interact pleasantly, so if there is anything, please comment before purchasing. Please be sure to comment before purchasing. Let's have a pleasant exchange. Thank you ☺️
