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 two covers 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, etc.! I wanted a black, mature feel, and I collaged it completely to my liking. * Because it's a "訳あり" (slightly defective) item, I attached covers on both sides and collaged both sides, making it super cute♡ ★ Set Contents ★ ・ Resin binder ・ Ring hardware (silver color) x 1 ・ Handmade refill for bills x 5 ・ 2 covers ・ White ribbon key holder 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 these are included as accessories and are not included in the price, so please understand them 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 item, please refrain from purchasing. Due to the "訳あり" (slightly defective) nature of the item, there may be fine 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
