A makisu is usually 25cm x 25cm, although this may vary. There are two variations, one with thick bamboo strips and the other with thin. Experts consider the thick mat more versatile, while the thin mat is designed specifically for makizushi. These mats come in various sizes.
After use, a makisu should be thoroughly air dried to avoid the growth of bacteria and fungi. Some cooks also cover the makisu with plastic film to reduce the cleaning effort after use. This is especially necessary for producing uramaki (裏巻) , a kind of maki sushi (巻き寿司) with the rice on the outside of the roll. Makisu are inexpensive so people can simply dispose them after use.
