I used a few sheets of KOKUYO A4 tracing paper, 75g/m² thick. There are about 49 sheets remaining (there may be some counting errors, please forgive me). The bag is also slightly dirty and torn, so I'm listing it as "slightly dirty." - Brand: KOKUYO - Model Name: tz-T79 - Size: A4 - Number of Sheets: Less than 100 - Thickness: 75g/m² Please refrain from purchasing if you are concerned about minor details.
