This is a cutting mat from L'Éclat de Verre, a French shop specializing in illustration and cartonnage. It's a large size, with 1-centimeter grid lines and right-angle guidelines, making it very easy to cut carton. I think it's difficult to obtain in Japan. As a bonus, I'll include a 40cm non-slip metal ruler purchased in Belgium. Size: 60 x 45cm There are two cutting mats available. 1 mat → 4400 yen including shipping 2 mats → 8200 yen including shipping If you would like two, please comment before purchasing (^^) Due to the high shipping costs and the difficulty of obtaining this item, please refrain from price negotiations m(_ _)m
