This is a set of 12 refill sheets to help you save money for a year♡ Each sheet can hold about 30 bills♡ I've created this refill set so you can manage and save money freely, one month at a time, for 12 months (o^^o) Please use it with an A6 binder♪ Handmade binders (resin binders) are also available! You can purchase them together. Because they are handmade, there may be slight misalignments or waviness. Please understand.★ These are the refills seen in cash management and saving videos popular in Korea and overseas. Because they are double-sided matte, you can check them with colored pencils, pencils, Frixion pens, etc., and erase them♡ Water-based pens can be erased by wiping with alcohol♡ Some pens may not erase, so colored pencils and Frixion pens are recommended! Please use them repeatedly♡ Please refrain from purchasing if you are looking for perfection like a mass-produced product, as they are handmade. 【Size】 17.3cm・10.0cm
