Everything is handmade. I use Frixion pens that disappear with heat and water-erasable chalk pens. If there are any remaining marks, I apologize, but please understand. I try to make them carefully, but there may be some slight distortions or misalignments. Please understand that this is a handmade item by an amateur. Height: Approximately 12.5cm Width: Approximately 19cm No pets or smokers. I will discount 100 yen for combined shipping. Thank you.
