This is a amateur creation. Please refrain from purchasing if you are looking for perfection. It is B5 size when opened. Made with thick drawing paper. Since there is no fastener, it will open as shown in photo 4. It will be sent in an OPP bag when shipped. Please check the second photo for the types of memo. OPP tape was made into flake seals. To prevent the back from being seen through, it was attached to paper and double-sided tape was applied. #ayyjewel #opptape #flakeseal #seal #handmade #osowakefile
