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 cover and five refills♡ Basically, I currently make items as one-of-a-kind pieces, imagining what I want to use, as an extension of my hobby, 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 for repeated use. Please use them for challenge sheets! I wanted a black, mature feel, and I collaged it completely to my liking☆ ※ Due to the reason for the defect, I made a very cute double-sided collage with a different atmosphere♡ ★Set Contents★ ・Resin binder ・Ring hardware (silver color) x 1 ・Handmade refill for bills x 5 ・Cover x 1 ・Black star keychain It is a size that can be used 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 how you use them, 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.
