Made of FRP (fiber reinforced plastic) Using high-quality pure silk Edo string Face of the frog About 400mm in length 170mm in width (200mm from chin to the base of ear) There is no jaw, so it can be worn by both men and women. Weight approximately 400 ~ 450g (There are some individual differences because it is handmade.) This is the mask you actually wear. Please check the size of your face. Because it is FRP, it seems to be strong against light impacts and not easily broken, Depending on how you drop it or subject it to shocks, there is a risk of damage such as the base of your ears. I make "light and strong" in mind, but compared to the same side of the brand, There is a weight for a long ear. For those who are familiar with the papier-made masks, If you suddenly pick up your face, it may feel quite heavy. The model wears a small woman with a height of 150cm and a face length of about 22cm. The author is a man whose face is about 26cm long, but his mouth is just blocked and his chin is out. In order not to come off easily, it is designed to be attached by tying a string at two locations, the back of the head and the neck. Also, please be careful of overhead. A mask band has been attached since June 2019. The feeling of wearing has improved dramatically. The mask that the model of the image is wearing is the one before attaching the mask band. Please note. At the time of purchase, please select the size of the mask band to be attached to the mask. Please tell us in a message or ask from here. Select S size for women or those with small heads, and M size for men. Even if a man chooses S size by mistake, it can be used. Since the S size can be adjusted smaller, we have prepared two types.
