This is a set of 4 saving challenge refills (*´︶`) Cute refills that let you enjoy saving money with each one ♡ Please use them with an A6 binder♪ Because they are handmade, there may be slight misalignments or waviness. Please understand. ★ These are the refills that are popular in Korea and overseas, and appear in saving videos for cash management. Because they are double-sided matte, you can check and erase with water-based pens or pencils ♡ Water-based pens can be erased by wiping with alcohol, but some pens may not erase. Friction pens and colored pencils are recommended. Please use them repeatedly ♡ You can insert money from the side, so if you have a lot of bills, use a clip to hold them ٩(❛ᴗ❛)۶ Please refrain from purchasing if you are looking for perfection like a ready-made product, as they are made by amateurs. 【Size】 17.3cm・10.0cm Type...Stationery Item Name...Notebook Item Name...Household Account Book Item Name...Envelope Savings
