Japanese-made mouthguard for Kendo Suitable for use with men (face guards) for boys and young children (13-bar and 12-bar men). Can also be attached to men for Naginata, etc. Made with a sturdy 1mm thickness. The material used is polycarbonate, which is resistant to impact and cracking. After various tests and monitoring, thin 0.5mm or 0.3mm mouthguards tend to come off the men due to the impact of strikes, or are more likely to break during removal (thickness is important, please check the thickness when purchasing). This product was created after determining that 1mm thick polycarbonate is the most suitable material for mouthguards. Please remove the blue vinyl before use. For multiple purchases: From the second item onwards, the price is 400 yen per piece when purchased simultaneously. We have plenty of stock, so immediate purchase is OK.
