Thank you for viewing! This is a square binder. Since refills were not sold, I made them myself, and this is an item for sale with one back cover and five refills♡ Basically, I currently make items as a hobby, imagining what I want to use, and create them as one-of-a-kind items, so I probably won't make the same thing again. ※ If it doesn't sell for a while, I will use it myself, so I may cancel the listing. Listings will also be irregular. The handmade refills have a matte finish on one side, so you can write freely with pencils and colored pencils, and erase them with an eraser, allowing you to use them repeatedly. Please use them for challenge sheets, etc.! I wanted a black, mature look, and I collaged it completely to my liking☆ It turned out super cute♡ ★Set Contents★ ・Resin binder ・Ring hardware (silver color) x 1 ・Handmade refill for bills x 5 ・Front cover x 1 ・Star keychain It's the perfect size for savings challenges, saving money, and using it for your favorite things. Size • Mini square (approx. 10cm x approx. 10cm) ※ The binder rings may be tight or loose depending on use, but this is included as an accessory and is not included in the price, so please understand it as a service item. ※ This is a handmade item created by an amateur, so it is not finished like a mass-produced product. If you are looking for a perfect product, please refrain from purchasing. There are some imperfections, such as small air bubbles and slight distortions. Please look at the photos carefully and only purchase if you understand and don't mind at all. To avoid trouble, we do not accept returns or exchanges. #minibinder #squarebinder #resinbinder #savingbinder #koreansavings #binderorganization #binder savings
