The Kevlar gloves that you described are designed specifically for use with Mr Babache fire juggling balls. They are made of fire-proof Kevlar, a material that is resistant to heat and flame, making them an essential accessory for any fire juggler. It is recommended to soak the gloves in water before juggling, as this can help to provide additional protection against heat. The gloves are available in two sizes, and the small size should fit most hands. It is important to wear protective gear, such as these gloves, when juggling fire to reduce the risk of injury.
